Hi, No! I'm not in the lab I'm in the old garage. well, not the actual old garage lab part of it, but here in the garage. At least because we're going to do a tear down which I didn't really want to do in the lab because well, if the Magic Smoke does escape, then I want to do it outside I don't want to do it in a, uh, big commercial building windowless building. So I'm back here in the garage.

so please forgive any audio or lighting or exposure issues or anything else. Anyway, I'm going to shoot this in 4k. We've got an Eco flow a Delta Pro uh 3.6 kilowatt hour battery here. thank you very much Eco flight for sending this.

It's awesome! It weighs 47 kilos I Won't even try to pick it up from here, but it's incredibly heavy and it's incredibly, uh, flexible. This is actually hard to describe. it's all sorts of things built into one. It's a 3.6 kilowatt hour uh battery.

So it's a big battery bank. It's got uh Mains outputs. It's an inverter, so we've got four for our 240 volt, 50 hertz Mains outputs Here it's got like a 200 watt. USB So I'll give you a brief walk around before we actually, uh, tear it down.

but it's basically a um, a solar inverter as well so it can accept up to four uh, full-size solar panel uh inputs as well like 400 watt solar panel inputs I think up to 150 volts so maximum it can. Also, it's also got charger build AC Like a grid charger built in so you can. charge it from the 240 volt. Mains and it's also got an additional input where you can charge it from type 2 EV charging stations as well.

So this is not only designed for home, uh, use, but it's actually portable and it's designed for. you know, if you've got an RV or something like that I Noticed that uh, everyday astronaut? um, he just released a video showing his OB broadcast band van. I'll link that in. Fantastic! He's using two of these puppies uh to power that entire van and it's expandable from 3.6 kilowatt hours up to I think it's 25 or something.

incredible like that. They've got also additional home panels as well. Anyway, I will be using this thing. so subscribe to EV Blog 2 Channel where I'll be releasing videos on me using this thing at home here I Plan on powering my fridges and freezers with this thing.

so I'll give you a brief uh tour around this thing and then you know, say here in the EV blog, don't turn it on, Take it apart. What we've got here is two nice big heavy uh molded carry handles on the thing and then we've got a larger display down here I won't show you the operation of it, but anyway, you can see that we've got two uh, 100 watt USB C outputs here. we've got USB A's and we've got uh USB a fast charge as well. And then we've got four Aussie ones.

Now that uh Yankee or european uh rubbish in there for Aussie plugs here, but it does come configured for different regions and stuff like that. one of them even I think one of the European ones has like a larger like I don't know 30 amp output or something like that. Anyway, this will be uh perfect. I'll power my free uh fridges from this.

but the trick is actually being able to integrate this to existing solar solution I've got at home and uh Power my fridges. Anyway, that'll be second Channel videos. and because it's portable, it does actually have a pull out luggage handle like this so they can just wear. it's got wheels on the back, you can just wheel it around.

Absolutely fantastic. Then on the side here we've got a flap which opens up which has a 12 volt 30 amp Anderson connector. here. this is for integrating with, you know, Caravans and you know Vans and stuff like that.

they're very common in that uh sort of thing. and it's got a 12 volt 10 amp cigarette lighter plug. Here it's got 12 volt 3 amp, a dual 12 volt 3 Amp Max outputs. You can turn those off and on and you can do it remotely as well.

It's got a Wi-Fi app as well and then it's got a remote control interface either Wireless or um yeah, it's like just an RJ45 and like basically the the front panel was basically available as a remote uh thing and then it's just got uh, pairing and stuff like that. um and I don't know what remote uh standby is I haven't uh, looked into that yet but that's pretty cool. and now I Love how that they've got uh, the extra little flap here for the remote control output. If you use, that means you don't have to have the whole door open.

nice touch. Then we've got another flap down the bottom here and uh, this is what they call their Infinity connector or Infinity interface. I Do believe it is a custom uh one, but anyway, it you can actually get an adapter that converts this into a type 2 EV charger adapter. would have been nice if it was like, um, standard, but anyway, that's an optional uh thing if you want to power it like if you're on the road and you've got your RV or whatever and you want a like a parrot and a type two um, charging, you know EV charging point.

you can just plug that in there nice. And on the back here we've got uh, two extra battery ports so you can hook up two batteries, but you can actually hook up more about battery storage solution if you go through the home hub panel thing or something like that that they've actually got as well. But yeah, you can add extra 3.6 kilowatt hour batteries to this. They just have like a raw battery uh version of it which is a bit cheaper because it doesn't have all the extra stuff in there.

And then we've got our um AC regular IEC uh Mains charge in here. We've got an electromechanical uh, really like this and I'm going to be making use of this. This is a uh either a really fast charge rate so you can power it, you can recharge this thing super fast. Uh, if you've got like a high current home Mains adapter or whatever.

So or you can set it up and I believe it's anywhere from like a 100 Watts charging rate up to you know you can program it right up to the maximum so you can customize the charge rate and that's really going to be useful for the application that I've got. And then you've got a solar input here which takes up to 150 volts. uh DC that'll so that'll take up to four regular large solar panels and I've got. They also sent me the outdoor solar panel for this as well which I'll be able to test anyway.

They've got nice big wheels on it and it is built like a brick. Dunny, it really feels like a solid solution. Then we've got cooling fans on here which are automatic are they will turn off and on although I think I've got a bit of it when I used it in the lab I was experimenting with it. One of the issues was I thought for the amount of power that I was drawing, the fans were actually a bit too loud so I'm going to have to uh check on that anyway.

cool air on one side, hot air out the other side. That's probably one of the disadvantages of this is that if you put the you know if you buy another battery and you stack it right next to it, of course you can have like two expandable batteries. It's gonna like block the airflow so you'd have to leave a decent gap between there between the batteries. So I'm not sure that is actually the best uh placement for the uh cool in there.

All right. So let's take it apart and we start by taking up this big rubber baby buggy bumper up here. and I really like uh, this and we've got a whole bunch of screws in here. so I think this whole top uh part of it is going to lift off.

but because all the different functionality in here I expect to find are possibly separate boards. One will be like uh, the inverter output board which will be the mains inverter output. here. we have another board for like all the USB uh, Power outputs and all the other uh, you know, cigarette lighter plug in the Anderson plug and all those uh sorts of things on the side.

So they'll probably be uh, separate boards and then we'll have a Mains uh charger board um, or at least a Mains charger section which uh, Powers it from the mains and then we'll have another board which will be the uh solar um maximum PowerPoint uh tracker board which will uh, be you know that you'd find in any regular um solar inverter uh and then we'll find uh, of course a huge battery uh, management board which has to do all the uh, you know, the cell battery management and balancing and everything else and also probably another board for uh, actually connecting through to the um, extra batteries and stuff like that. So I expect this to be quite modular. Let's see if I'm right, so this is a premium brand. You probably won't be able to buy much better than this.

so it comes at a premium price of course. So I expect this to be really good build quality. I'll be disappointed if it's not all right, it should just pop off and oh yeah, look at that. Whoa.

Nicely shielded. There's a sticker on there talking about, uh, some sort of um, spray free process which creates a unique aesthetic pattern on the product. Service that's eco-friendly somehow and it looks like these side panels are just going to come out. I Found two screws here.

so oh yeah, oh yeah, look, oh yeah, we're in there. You go, let's see the battery pack. So the battery management system must be on the other side. sorry, it's a plane flying overhead.

don't get that videos often. Yeah, it's actually a significant amount of space left in there. So I've got like the top of the range unit. Uh, there's like the honeycomb side panel.

Um, so yeah. I Don't know. They could have made that a bit more compact at least. but uh, I'm certainly not complaining about the size though.

For what you get, it's still incredibly. Compact And here's inside the other side panel here. Let's actually measure that. Shall we see if we get anything out of the battery? like two big bus bars going across that big screws up into the main board there? Nope.

Zip. Um, I did actually discharge this. uh you know, basically 99 discharge before I started. but that doesn't mean that like there's not going to be zero volts on the cells.

So obviously they're disconnected in here so it looks like there's a few more screws in here. Looks like I can probably I'm probably gonna have to take out the bus bar and then looks like this cover is for this huge battery management. Uh well, it tells you. Battery management system there it is that says EB signal I assume EB means extra battery.

Anyway, they've got things like there's a little uh six pin uh well no uh no. a couple of uh way header down there. anyway. Oh, we include high res photos of all this on the Eev blog website.

um, a few fan aficionados. There you go. I don't know. I've never heard of that one.

um, some Shenzen brand. So they've got voltage signal on here so all of these would be the individual and not each individual cell, but like each. whatever, how many they have in series or whatever. Um, however, they've arranged this uh pack.

they would be the voltage for uh, like the individual uh cell arrangements and then NTC over here that would be individual thermocouples for um, measuring the battery, uh, temperature as well. Nice. I'll tell you what. I'm impressed by uh, the construct action.

It's all really sturdy stuff. I Mean these are solid ads going up here to hold the top cover on because this is designed to be portable. It's designed to, you know, be thrown into the trailer, taking on, uh, camping trips, or you know, being used with your RV and then you take it out and you might move it around and stuff like that. So yeah, it's going to be really sturdy and uh, it.

They've really done quite a good job. Nice attention to detail. They got rubber insulating sleeves around here. it's all heat shrunk and it's all you know.

It all really is nice. They've got some celastic down there on, you know, holding on the little interface connectors and stuff. Neat. Looks like this board on the top here is going to be our solar inverter.

That's going to be our maximum PowerPoint uh tracker board so it's probably might take up the whole lot. Um, but anyway, it looks like it's got multi layers uh on here. so we have to get all these cans out and uh, yeah, might be a multi-layer cake. and I'm really impressed how all of these uh, front and side panels and stuff are really, uh, held in.

They've got washers on them. they go got captive nuts in there to actually hold them in? it's all you know. they've put a lot of effort into this. It's not shuttily constructed at all and you can actually see you can see the captive nuts up under there as well.

Nice. Okay. one thing I'm not keen on is the little uh Spade lug terminals here. I know why they've done the Spade lugs but that is that's loosey-goosey um I had to take that off to sort of like get this, um out and uh, the Earth connection as well.

Yeah, I'm not not not happy with that at all. That is like really loose. I'm gonna have to like crimp that back together I don't want to use it like that whereas this one over here this is tight as well. I'm not getting that off.

um, that's going to be quite an effort. but yeah, the mains input connector I think they need to do something about that now you can see the extra battery input Uh, board here. Huge bus bars snake around, they fold up under and go over and connect the two like this? Absolutely, uh, fantastic. And the mounts on there are really solid as they got.

They're not just a plastic standoffs on there, you can. hopefully you can see that's a bit black down in there. But um, yeah, there are actually quite solidly constructed those standoffs. So, but these are PCB Mount connectors.

But each one's got actually four bolts actually holding it on so that that is really quite neat. So it's really, uh, quite something. And the looks like the little management board down here for that. I'm going to be doing sensing the stuff.

It looks conform, really coated the top of that micro presumably there. Um, that does actually look nice and shiny. conformally coated. The rest of the board isn't though.

but so yeah. I'm really liking that interface. and you can see the bus bars running under there. They'd be going over to the battery uh, management board in here, which we can't see yet.

and there's more of those uh, cage clamp nuts all embedded in the plastic. This thing is really built like a brick. Dunny. It's solid as it's like a big monolithic block.

There's just the wheel Mount down there for those uh, playing along at home that looks really solid that's all integrated into these big plastic things. It's uh, bolted down in there and done. Yeah, It's once again, the the base is not metal though. the base is all uh, plastic.

but it's thick as and like ribs everywhere. It's great stuff. There you have it. The front AC board just swings out there.

once again. all these captive nuts down the side. here, captive nuts down under the bottom here. Just had to undo a couple of uh connections which go up to the main board on the top here and and we're in.

So there's our Wi-Fi module in there. So it's mostly just our power supply on here because this is all the USB stuff on here once again. I can see conformal code? all right. I Think this entire board is actually conformally coded.

It's nice and shiny, but these are the 100 watt USBC outputs here. These ones over here are the regular USB A's and this one over here is the USB A fast charge over here and uh, and then just some LCD stuff as well. flat Flex ribbon on the top there. Yeah, so I'm not sure if you're going to be able to see, but uh yeah, that is.

uh. nice and smooth conformal coat, nice clear acrylic on there. For those who don't know, that's going to keep out moisture and stuff like this because you're going to use this in like a moist environments. you're going to use it.

camping. It's going to be out in your garage. It's going to be in your trailer. it's going to be.

you know, in your RV it's going to be like all sorts of things so you definitely what a nice conformal coating on there Anyway, that definitely looks like what you'd expect in 100 watt USBC interface. So you know you could power like a couple of laptops directly from this thing. Of course you don't. If you're using these in the wild, you don't want to.

actually. um, as a last resort, you would use the 240 volt AC output and then use the extra converter the regular Mains to USBC uh power brick that comes with your laptop or whatever. You would plug it directly into this because you're going to get the you know you don't want multi stages of conversion losses. you want to minimize those losses.

So yeah, if you can, you'd be powering your laptops or whatever you can directly from the USB C outputs or the regular USBS And the same thing goes for like the 12 volt cigarette lighter adapter and the Anderson uh connector on here and the 12 volt outputs. If you can power stuff directly from like the 12 volt or USB outputs, then you're going to get the most efficiency out of your battery. There's nothing special doing on the Mains board down in there, but I do like the big cage clamps here that they've uh got and they're Then it's just um, the PCB soldered Mains connectors directly in there. There's nothing wrong with that as long as you take the strain on the front of the case, which is what they've done.

So yeah, that's that's a really nice uh solution. all the like. They've got any Shake washers on here. by the looks of it, it's all very nice and the cable management is all very nice as well.

They've got a cable tied, they've got a heat shrunk where it needs to be, and then when cables go directly through metal work here, they don't just rely on the heat shrink. They have an extra rubber surround here so that you know any Burrs on the metal work, don't cut through. India Cables really is quite a professional solution. I'm very impressed by uh, the design, build, and construction quality of this thing.

but then again, you'd want it. This thing is like top. You're paying a premium price for this thing and it looks like with this battery pack here. apart from being like one, one big molded plastic uh enclosure for it.

Looks like they've got some steel stiffening bars in here as well and that's very nice. I'm not sure what. um, it, maybe that just connects the top part of the plastic to the bottom part. Not entirely sure.

I'm not going to take all the battery uh system apart I just want to look at the boards and I Forgot to mention this is lithium ion phosphate, not your regular lithium ion. so there's safety advantages there. There's uh, like cycle life advantages and other stuff. I think this has um 66 000 or something Cycles to uh, 50 something like that.

so it's It's not too shabby. so you want your interfacer for your EV connection down here to be fairly rugged. It's got its own metal plate there and that looks really solid as so. I'm quite impressed by that.

That's the infinity I Guess that's their own thing. It's their own adapter interface I think and you've got to get basically a conversion uh cable for it if you want to type, you know, convert it to a type 2 or whatever EV system solution you've got in your country and all the board-to-board interconnects in here are very nice. they just pull out PCB Mount so I think I've got most of them off now so I should be able to start to get these cans open all right. Should be able to lift off the inverter or the maximum PowerPoint tracker board.

Yeah, no, it's still something I'll get back to you. And here's the Solar Mppt board which is the maximum PowerPoint tracker. so it takes the solar input over here. This is the main connector which then just goes an extension cable off to the solar connector on the front panel and it's basically just a regular solar inverter that you'd you know find in any regular house.

we've got our then we've got our downpour from here. Got our switching transistor arrays here and as you can tell by the shine on here, this is all conformally coated once. Oh, there's a reset button on here. Um, there's some sort of button.

Um, there's yeah. I like that I wonder what that does? might have to press it anyway? I'll put some high-res photos of this up and we could potentially go through this at a later date. but I don't want to analyze the design of a maximum PowerPoint Tracker here, but uh, supposed to say this looks really, really good. It's a nicely laid out and of course there's going to be lots of lots of nice airflow as well.

They've got the fins on the back of the heatsink here, in the right orientation for the airflow to flow like actually across them from one fan in cool air in one outside, hot air in out the other side. so that's all really nice. I Like it and there you go. We have a big relay disconnect over there.

unfortunately I'm not seeing any. uh, like top quality brand caps in here. these are Samsung So yeah, not the best. It's a bit disappointing for like a top tier brand like this.

So what? Give me some Panasonic Jobbies looks like we have a ceramic fuse there. it's just flapping around in the breeze I Don't like that. like all the other attention to detail look, the relay is held down with Silastic but they won't celestic the fuse in there. They've even got celestic on the on the power resistors up here to stop these flapping around.

like because of course this is portable so vibration is going to be a big thing. So down here we've got some surface mount fuses over over here. These would be for like really gross. you know something seriously goes wrong with this thing.

It wouldn't be for regular protection and likewise on the solar input. over here we've got some PCB amount gross overload fusing. but yeah, that's only if like the circuit fails and it just basically protects the whole thing from blowing up. I Stand corrected.

there is some celastic right down the bottom I just couldn't see it from the other angle. Still, it's not much and this thing still does flap around in the breeze. and once again, these uh Power resistors down here as well. They've solastic those down and the Caps as well.

So you know they've thought about the vibrational aspect of this. If they're thought about moisture, uh, protection in the environment and stuff, you can see the nice shiny coat on there for the acrylic conformal coating. actually. the output caps here.

they're um, a shy brand so they've gone for something different there. they're actually uh, you know I think they're a fair bit better than uh, you know, caps on. So overall I Gotta say I'm liking the look of this. uh maximum PowerPoint Can sure? Well, they haven't tried to cram it down onto a small board so that's nice.

And the way they've done the airflow and everything seems, yeah, it's pretty good. It's worth the money and here you go. This is really grunty. Um, this looks like it's a combined um AC Mains uh charger and also uh, the inverter system as well.

The main inverter system for the Uh Mains outputs so huge big heatsink arrays here. Temperature sensing. These aren't just these aren't ground wires, these are actually, uh. temperature sensors there sensing each heatsink.

Very nice. Not sure what this Plate's doing over here. Maybe it's got a temp? Oh yeah, yeah, it's got I see a temperature sensor wire going up there so it's probably got a temperature sensor on the bottom side measuring the heat Sinker temperatures. So lots of thermal overload protection as you'd expect.

Tons of relay switching over here so they're all solastic together so they don't vibrate when you wheel the thing around and handle it and transport it in the back of your Ute and check out that little current Transformer Now down there it's very nice. You've got a big thick as a jumper and then the current um Transformer there. so that's a that's got to be measuring. uh the main EV uh input I suspect and you can see same current Transformer down in there as well.

That's very nice. Anyway, this is all near the battery over here. This is like the two main battery terminals going over, uh, to your main battery bank. Here it looks like you've got lots of uh, shielded magnetics happening here that looks very nice.

Anyway, yeah people are you know they've gone to town with this elastic gun. Everything's like Silastic down for any vibration and everything else. but um, Interestingly, this entire bottom board doesn't seem to be conformally coded. but this board up here.

whatever that one is doing there. oh, that's a fan. that's fan controller board. It is conformally coated so I don't know.

and we've got our battery pack voltage this 65 volts DC 50 amps there. So yeah, we've got three fuses here. they're actually all in parallel. actually tiny little things.

um, but that will protect the pack if uh, anything goes wrong, ski I've taken off the Big Bus bar battery assembly here and uh, hopefully I'll just be able to lift out the charger and inverter box. Yep, that's it. There's just two connections. I'm really liking how modular this thing is.

It's absolutely incredible. and now I can really see the big cage actually on here like this with all the big standoffs for the uh top of course that carries all the handle. Ah wait, uh, because that the handle assembly is part of that top assembly and this is just once again, all the cage clamps and everything and your battery packs inside here. But it's everything's.

completely modular. You can take it apart. It's something you know if a module fails. I Was a bit surprised that the charger and inverter assembly is all on one.

I Sort of expected. Uh, separate modules for that. But anyway, yeah, they've done on the one big board. Isn't it beautiful? So we should be able to get our BMS cover plate off now.

and this is going to be one big ass board. It's going to have a lot of stuff on there because it's a pretty decent sized battery. Plus, it's got the two battery expansions and these are the first self-tappers that I've actually found. but of course you wouldn't be taking off what this cover very often.

Yep, Yep. oh, we're in like Flynn Check that out. Isn't that gorgeous? Wow! And once again, this is entirely conformally coated. And look at these huge battery.

uh, bus bar connection points. There's no uh wiring in in the battery. It's all these uh, metallic bus bars over here. These go over to the expansion pack.

This one here goes over to the battery input. So yeah, I think that's that one. Probably snakes its way under there over to here. um, and a battery.

Miner So that's that's the main battery pack there. And then you've got two expansion uh pack inputs here. and yeah, it's got to, um, switch these in. So yeah, it's not.

It doesn't look like it's doing the actual battery management here, which is like yeah, you wouldn't really. um, expect that. Um, you'd want that over on the other pack because the different batteries this internal one here could be at a different uh charge state to the first expansion one and the second expansion one. So they've got to have their own, uh, not only battery management, but their own um, cell balancing.

and we can see the cell balance in here I can't make out these chips because the uh, really glossy enamel, uh coating on these. It's like I don't know I'd have probably have to get it back to the lab and I get the light sources in all different areas in the microscope like at different angles in the microscope and stuff. Anyway, um yeah, so these are all our balance inputs here. coming from the uh, this is internally, uh to the pack, which is where these are buggering off too.

These are temperature sensing inputs so how many Uh channels we got? so I won't bother to count those? uh, those plan long at home can count those to see how many um, basically different uh strings that it's got uh within this pack. Not sure why they got this extra board here. It's got castellated edges, three volts. Aha, that's the Bluetooth interface here.

I like I've tried the Wi-Fi app and it like it worked I was able to get it working I don't know what the Bluetooth does like I couldn't have an option to connect to the Bluetooth I don't know. I might have to Rtfm again. but and next to that is a little switching converter. Is it looks like it? um, looks like a bit of custom magnetics there I Love these.

Uh, two whopping power resistors up here. What are they doing? Um, not entirely sure. but anyway. um, there's only one.

like one pair of those. Like there's no matching ones for the other channels. So yeah, not entirely symmetrical there. And why? they've got extra, uh, thermistor inputs here.

That's what the NTC is. they've only got. Well, actually, none of those are populated. They've only got that one there that there's populated.

Um. I can't remember where that went off to I Don't know. I'm going to put it back together to figure it out, but uh. anyway.

that is one monster complex. uh. battery management board. It's very impressive and of course you're going to have like two entirely different sections.

This this half. it'll be split like this. This is for battery. Uh, one.

all those mosfets there. they'd all be in parallel I Wish I could see what they are, but I can't unfortunately. Um. and then once again.

uh yeah. it's got some more switch in here and another array of switching over here. and 200 amp fuses in parallel there. thank you very much.

Wow, this thing's just pretty beasty. Found another little secret button in there. which looks like that's been hand soldered on. You can still see the flux residue about there.

Um, so that's about the only. Um, yeah, that's the only issue I found with uh, the soldering in this. So that was um, like yeah, an extra step after thought. doesn't look like that was a reflowed in place.

So the mystery micro there don't know can't tell you that I'd really have to get uh, some light Solutions onto that to try and peer through that conformal coating. And now we'll actually be able to measure the battery pack. Make sure I don't don't have it on the current input. That would ruin your day.

So battery negative, battery positive and 46.39 volts thank you very much. So yeah, however many like string arrays they've got in there, based on how many uh, balancing channels they got in there, that will be the arrangement At first I thought these were a bunch of Poly switches in parallel, but they've got r on them and so they're obviously parallel resistors. They're actually using those as a big current shunt. So to connect the um I guess the system power ground to the battery ground and there's no switching in there so there's no way to disconnect it and you should be able to see.

there you go, Some tracers running off up there. You should be able to see traces running off. so they're actually using that as current sensing. So yeah, they're doing it.

Looks like they're doing that low side. Uh current sensoring, current sensing for the main pack. so you can see our charger and inverter board a bit better there now. and on the charger inverter board, you can see that there's a little board down there it says um, silk screen Mr500, Cntl so some sort of control board.

It's got a little window here to access some dip switches when you, uh, take the cover off. So yeah, I'm not sure what that's doing. Um, it's not like setting an address for the battery or anything. I don't think maybe some I don't know a different configuration depending on uh, what unit they're actually assembling for different regions.

maybe? Yeah, so it looks like this is the Uh 240 volt input over here. Then you've got a huge monster varista there and then a typical common mode choke scenario there and it looks like you've got your Y-class cap down to ground there. Then you've got a full wave Bridge rectifier and uh Mains uh filter cap. So yeah, that's all.

it's uh Maine's potential. so the physical arrangement of this thing doesn't make a huge amount of sense. I Mean you know AC input here, that is this. um I can't see anything made.

Is this like the charge? This might be the mains charge controller maybe can't see the bottom side. They've got huge massive um pin standoffs there, so I'm not sure what's doing there, but uh so this would be your standard bi-directional uh charging so you can charge the batteries in that direction. So Mains input over here or solar or wherever it was coming from over here I believe. So it can like switch those in, switch to different inputs that's what the relays are there for and then it can go through in this direction through to your battery over here.

So looks like we've got two separate stages here. I Won't go and try and like figure it all out and decode it all. I'd have to sit down and have a think and draw it all out and stuff like that. but basically yeah, it allows you to um, charge your batteries in this direction from the switch from any of your sources over here, over to where whether or not comes from your solar Maximum Power pointer controller or your 240 volt.

uh Mains input over here and then it also allows you works as inverter so it comes out of the battery and then 240 volt. uh Mains inverter output over to here and then it can bugger off wherever the mains output is there somewhere. Yeah, so ultimately you've got Mains charging. You've got solar charging and you've got uh, your? EV um that Infinity connector input I don't know which ones what there, but yeah.

anyway. um yeah. three different main ways to actually uh charge this thing and where's it getting the mains out? But this thing. you kind of lose track when you uh, take this thing apart? ah yes I do believe that one.

There is the charger output which is that one there so it's rather complicated. but I don't think I can Goof this up. uh, putting it back together right? I think I got all the screws. yeah my screws off the top plate.

Looks like we can get the cover off the battery plate here. Okay I just expect to see. Did I get it? Yeah, just expect to see some terminals. probably not a huge amount.

Yeah, there it is. There's the uh, yep, there's the connections going over. nice heat shrink tubing, very nice and um, it looks like I have access to the individual cells and we got rivets in here. not sure how well you're seeing that, but there you go.

you can see inside there and you can see some rivets see board rivets there. So they've riveted everything to the board so they do that as maybe a different assembly. and by the way, I do have a link to a video to uh, an Ecoflow factory tour I haven't watched the whole thing but I skimmed through it and does look interesting. It shows you how they manufacture the packs and uh, well, at least you know the various processors and assembly steps and stuff so we should be able to measure like just various random uh voltages.

you know 9.2 you know, 24, various random staff, 27, etc etc. So they're the main contacts. How they do that underneath I don't know, sorry I don't plan on taking apart the Uh pack any further than that. Oh, and once again, these are one of a few self-tappers in this thing.

I am very impressed though by how this is uh assembled in all the cage nuts and the clamps and the modularity and the real thick as ABS molded plastic and the heavy duty metal work this is. This really is built like a brick dunny. and uh, for those who don't know, brick dunny is, uh, really super strong here in Australia and uh yeah, you really are getting your money's worth in this thing. I Think it's certainly not built down to a price, it's built up to a price and well, yeah, this is one of the I I Don't know, you know the entire market for these things, but I believe it is one of the better, more expensive brands on the market.

So there you have it. There's the tear down in the old garage of the Ecoflow Delta Pro battery and so thank you Ecoflow for sending this. and as I said, uh, subscribe to my Eev Vlog 2 Channel LinkedIn up here and down below uh where I'm going to actually uh, all my fridges and freezers I'm going to turn this into a solar inverter so that I can power up my fridges and freezers and have backup power solar power. So I'm going to integrate kind of semi-integrate that into my home here.

But the cool thing about this is that it's completely portable. You can take it anywhere, do anything with it. So great camping solution or something like that. it'd be great for Preppers if the brown stuff hits the fan, just grab your uh ecoflow battery and off you go.

And I've got the portable 400 watt folding solar panels for these and they look really Schmick as as well. so I'll do those um over on the second Channel where a lot of my art solar kind of stuff goes. But anyway, this is a very impressive tear down. Very impressed by the design and build quality.

Hats off to the to the you know the mechanical and system design Engineers how this has all really gone together and it seems to use it apart for I would have preferred like higher quality caps but and this is a Chinese supplier so I guess no they're not going to use Japanese caps right? But I am very impressed. The design and building component quality otherwise seems very excellent. Lithium ion phosphate batteries inside this thing which should give a longer service life and also uh, you know, a little bit safer than your lithium-ion um cells. So yeah, I get this was really fun I Enjoy this.

hopefully it goes back together okay but the modular construction of this unless I actually forget to plug something in. um all the cables are like the cable management and everything is beautiful. I Really like this. So anyway, hope you enjoyed that.

If you did, give it a big thumbs up, let me know you know, think about doing videos in lab again. I Got this portable workbench I think I really enjoy this I'm enjoying the um, the cameras outside my roller door here getting fresh air. it's fantastic and I'm getting light from outside. Let me know what you think.

maybe not as good audio, uh, quality and maybe uh, you know, color balancing or whatever and all that sort of jazz. so it's not as controlled in an environment as uh, the lab. but I'm really enjoying being back here in the garage so this is absolutely fantastic. Can have fun with this.

So anyway, thoughts and comments down below catch you next time and yeah, I won't give up my day job trying to put this back together at least. I uh, sacrificed to the tear down gods and yeah, having just reassembled this I'm actually uh, I'm very impressed by the system design of this. It's absolutely brilliant. Um, that's just the way the cable management and the modularity of it and the way it all assembles and uh yeah, just got some sharp metal on there.

but no, this is really good. Yep, the only issue I have is the Spade lugs on those Mains connections. They're just even if I tighten them up I I Still don't it's not. They would have preferred.

um, a properly soldered in there and then screwed over. Well suppose I better make sure it actually uh works. So let's power it on. There we go.

As I said, it's uh, pretty dead. so I'm gonna have to charge it. but uh well, it does. Come on.

Okay, let's plug the mains in. Yeah, heard some relays see some leads in there. There you go. she's charging.

No. Walkers Looks like it's going to take 10 hours. Yeah, everything looks hunky. Dory is charging at uh yeah, the minimum.

Uh, 400 watts or that's what. I've got it set on slow mode. It can charge way faster than that. Catch you next time Foreign.
