The electric go kart is looking more and more complete!! In this video we install all of the other components that will be needed for this thing to be ready to rip! It still has a ton of wiring to complete but this is one step closer to the final product. We have never done anything like this before but we are excited to take you along for the journey!
Thank y’all for watching and be sure to stay tuned for the next step of the build!

Welcome to the electric cart, build episode 2 in this one, we're gon na add all of our accessories as well. Get our batteries mounted up. It's looking sick y'all stay tuned all right, so this is what our battery stuff will be like when we first got them. It was in these groups of six long and too wide, but this is a little bit too wide and a little bit too short for a cart, so we rearranged them.
So it's three wide and four long on the rotary cart. We have problems with not having enough weight up front, so this will definitely give us a lot more weight up in the front and we'll probably have some better handling. It's gon na look so cool, oh yeah, so we have two clamps that are camping. Each little group of six together and then we've got one big clamp going along the entire length.
So I'll give us a lot of rigidity and make this super strong right now. What I'm doing is unscrewing all these little battery management system, chip, things and then later on. I'm gon na have to see if we can use this right now the wires kind of look a little trashed, but hopefully we get that working. Then we'll have a little battery gauge and everything.
Now what we're doing is we're strapping together. Our two groups of six cells, and basically all it is - is just these last straps. This is actually my last one I'll work on this for the last few hours. So I'm glad to be done with it, but now I will do is once we're done with these.
We can get it mocked up on the cart and start getting a mounted basically right beside the passengers areas all packed together and really nicely next to our seat, and basically, they fit perfectly within the existing bars. So we'll just be able to slap the old plastics on really easy dang that is going okay, all right, so yeah we got kind of lucky with this seat, pretty much all the mounts. I mean with a little bending and re welding, but they're pretty much all good. You know.
Extra fabric is required, making our battery mounts. It was actually really simple, just angle, iron on the two sides and then flat stock and then to support the bottoms. We have this thin plywood, which should be plenty strong and then for some little vibration resistance. We got this horse matte horse stall, matting, so yeah.
It should be pretty safe and really strong and it fits really tightly. And then we just have to make two little straps from the top to hold it down and we got our mouth. So we are now totally finished with our battery trays and mounts on the way we're holding our batteries in is actually kind of trick. The only thing we needed is something to keep them from going up and down so there's little threaded holes in these brackets that we used and basically ready right here we made little mounts that is going to go through and utilize.
The whole list in the battery. In the screws we've got that side done, we'll get this five battery in and then we can start working on mounting up all our other little components and stuff. So we finished our fuse and converter mount. It ended up being pretty nice. Just I mean some square flat stock, but that will mount up right against the back of the batteries, love our power coming into the fuse, and then this will go to our contactor. So that's what we're mounting next alright! So we have the converter in the fuse. All tacked in the mount up and right now, I'm just working on installing the mount for our contactor, which is basically just a big DC relay so yeah. This will just stick off this part right here and get the wires going up there and it's good to it.
It's motor controller time. So it's just gon na get mounted on the seat and we have these two metal bars here flat stock and basically as simple as lining up with the holes, drilling them out and then we're gon na weld this down here where it fits. But let's go some hole so we're mounting up our motor controller. We added some cool triangulation with some gussets here super cool stuff.
So what we're going to do is we're going to tack this in and pour some water on it. So we don't melt this stuff and then we'll pull her off while it's fully up and then I'm pretty sure all of our little components are mounted up alright. So all of our mounts are done for all of this stuff. So right now we're just going to slap everything in and look it's a final look at this all right.
So here's our last piece and motor and Athena - and this is pretty much exactly how it will be lunch driving of all the wires dang yeah - hey we're pretty proud of this okay, I like it too. I would do it guys so much for watching. I hope you liked how everything turned out. We kind of went all out on mounting up the systems and stuff, because we want this stuff to be really strong.
The batteries aren't going anywhere. All of these components in the back aren't going anywhere. So with that being said, stay tuned to the next episode now that everything's floating, where it needs to be, we can wire everything up and hopefully see this motor spinning we've actually never gotten it running before so we're hoping all this stuff we bought on Craigslist actually Is going to work out, we kind of built it before we checked it, but I think it's gon na be all good, but thank you guys for watching. Thank you.
Go power! Sports! We'll see you next time. You.
Adding a lot of weight. Why not dril some holes in the batt mound floor to safe weight?
Also that sprocket on the motor looks to big. Not only will that be hard /slow to start but I think it will put too much load on you motor and without cooling it can over heat the motor and burn up. You said your running 80v battery and controller to a 72volt motor that will be fine but that also adds to the heat so that and the sprocket will be a lot of heat please cool it and change the sprocket. Just my two cents.
Hey guys I hope you all seen the comment by “Kit Iwamatsu” please read it as he is correct. You need to use the BMS (battery management system) you should not even charge these batteries until you deal with it. I’m not gonna go into detail on it as the comment by Kit is plenty but I don’t see many likes or over comments on this and it’s the most important part of using lithium single cells. Please read it. Love this project it’s a perfect platform and I’m excited to see it finished.
Hmm… I'd have mounted the controller on the other side of the batteries, those fins are for cooling and behind the batteries you're losing out on potential airflow. It'll still work, it's just not ideal.
That's awesome that you guys are doing the electric go-kart I haven't seen too many other people doing them I'm sure there is other people on here somewhere doing them but none of the channels I watch I remembered I had recommended it a while back and probably has a bunch of other people did too that's awesome you guys there doing it keep up the good content
Nice job I don't think you have to worry about the batteries going anywhere looks like ya built that part really good can't wait to see it running
I did this 20 years ago with a motor from a CCE hydrolic pump and two Batterys on a trick frame. It was pretty quick and did nice burn out!
How much torque? All the torques
That’s going to be so much fun and over time as battery tech improves it will only get lighter and faster. I want one!
I sub just cuz ole boi is rocking the jerry curl lets goo haha my hair is same way thats why i cut it but the ladies love it lol
This looks like it will be almost as much fun as the Hercules rotary kart! It ought to rip pretty good, and considering the overall diameter of those tires, your gearing should be pretty close if that's the motor I think it is. Better get a heat sink for your motor controller though, or you'll be buying a new one pretty quickly.😉
That motor controller needs a heatsink.
If you try to put it through its paces like this, you'll destroy it.
Guys. Please get a proper cordless drill. And make some (non conductive) covers for the batteries.
The BMS does more than just tell you voltages. It also maintains individual cell voltage levels when charging, and should have a cutoff solenoid to protect the batteries from over discharge/charge. Those boards have resistors on board that a mosfet turns on once the cell reaches it's proper fully charged voltage, to help balance the cells. It is not safe to charge those cells without a BMS, or a charger that monitors your cells. Since you're running what looks like 1p12s (12 cells in series for 44v nominal…) you're going to a 12s balance board, or at least a 12s capable balance charger.
I'd get your BMS working before attempting to charge, since i assume you bought a complete setup. And check all your battery cell voltages. If you cannot get a BMS running, or their voltages are not matched, charge them one a time to full charge with a sizable single-cell charger before finishing the pack.
If you're charging the whole thing as one series pack, you're going to need a 1p24s, which means you need to get that BMS working. There aren't really any 24 cell balance boards or balance chargers out there.
I'm hooked on the intro music, and I'm 55 years old. I call it easy listening. Andy
Unsubscribed because of your stupid method of leading people on with your videos. This video is everything I don't care about and already know.
I think the acceleration will be more exciting then the top speed, great work 👌👍
Love your videos. Can't wait to see this beast run. One request, don't spoil the ending by showing it at the beginning of the video. I rather see your progress to the end. Good work guys.
Awesome work as always! Be interested to see how much it weighs once finished.
I would love build something like this put a few alternators on it run by the axle see if I could get it to charge y its driving be a fun project
Throw out the bent twist drill. Someone's gonna get hurt. Great job anyway.
