This is so cool. I've never made a gokart before but I want to make an electric one before summer. What motor are you using for the old cart and how fast can it go?
Man I'm really worried about you driving around on roads and parking lots that are full of people who are too distracted to notice you. Please don't get hurt man and wear a helmit.
@@Kevin.OBrien44 That's good. Sometimes you can't stop quick enough, you know what I mean. I've seen people just back out without looking. My wife's car was hit in a parking lot, the guy was found at fault, which is rare in a parking lot incident where typically neither is at fault. In this case the damage indicated that the guy backed out at such high speed that he was considered to be driving unsafely. My wife said, he flew out of the spot.
This is the sort of stuff you do when you're young and think you're immortal. Kudos for your aptitude, but karts are impractical and 100% illegal and obvious on the street. Stay safe young fella...
that’s why i went with one so thick. so it wouldn’t do that. i actually had it slip so i checked it and the motor bent my 1/4 in thick steel motor mount. so the belt is just fine for now
It just came to mind, why do you have three on/off switches for the kart (I saw you have two on the dash and another on the controller I think) as well as a key ignition? So you need to turn four things on before you can get the kart going?
I was going to have one for a reverse and one for forward and one for power on, but i broke the reversing contactor so now the key is power to the esc and both switches have to be on for the contactor to be energized.
Yeah I actually just sold my old kart a couple months ago, but I'm keeping this one for now. Maybe ill sell it in a year or two but ill let you know if i remember
Sick build dude! I just built one as well and made my own series on my channel- very similar, just some different parts and not quite as fast as yours but very fun to make!
Hello, I want to make a electric kart. I have allready a good motor, what controller should I use and what batteries? I want to make a budget Project for start.
Not sure because i got it used from ebay. It weighs about 45lbs and has a diameter of 6 inches and length of 9 inches if that helps. Also the rpm is somewhere about 3200 i think.
We are about to build one of these but ATV style! I am thinking about using the SAME Kelly Controller with Regen, and I want to use a belt drive system. I saw your other video where you made the belt system. Do you have any advice on the belt drive, where to get the parts for it? Also, have you figured out how to connect a speed meter and volt meter to the Kelly Controller? There are a lot of pin outs on that thing that might be useful. I was thinking I could interface an Arduino or circuit python board that drives larger 7 segment LED displays for amp draw, and volts and maybe some kind of batter level meter (that's a whole project for a different day). For speed, I could always just use a GPS meter. Does the Kelly Controller NOT have reverse or is that the limit of your motor? I'm not sure what motor that is just from looking at it.
The reverse function is actually done with a special type of contactor called a ''reversing contactor''. The pulleys I Got them from ebay. I think they were for a dodge trucks timing belt. www.ebay.com/itm/362443468929?nma=true&si=nDtp5PkJAwgWS6dfQbF%252BhjcBZyE%253D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557
@@Kevin.OBrien44 thank you!! This is helpful. We are converting an old mini ATV to EV using a lot of the same parts and Kelly controller too. I think the belt is the way to go for electric!!
Yeah you could definitely do it. you'll be on UA-cam watching tons of videos to figure out how to do it though. I think I spent less than 2,000 on this one and only 1000 on my first one. When your deciding to use a brushless motor or brushed, the brushless motor setup is going to be more expensive but better for high speeds and the brushed motor is gonna be a lot cheaper.
Have you seen the free energy generators uses a alternator and a 12 volt DC motor and it pretty much runs itself and it creates 120 volts it's small enough that it would fit on this go kart and you wouldn't have to have the need for batteries
Hey so I was going to build something similar to this but was trying to find a cheaper/lighter alternative to the motor do you think a Amazon/eBay China motor would work I was going to do a Kelly 72v controller and a 72v 40ah battery and trying to get a top speed around 45mph or more
I think I've spent just under $2,000 on this and I'm not taking orders to build for other people but I might decide to sell this one if I build another so keep your eye out for updates
I got to a top speed of 50 mph on gearing that was too low, but i messed up some of the battery cells before i got to do a new test with better gearing. so all I know is that it could do like 0-40 in about 4 seconds. hopefully, I can get replacement cells and do a real test eventually.

hi my friend. Whats engine you use in this project? You use what batteries? What time duration, in use, your batteries?
the motor is from a electric forklift and the batteries are a123 systems. I get around 10 miles of distance or 30 miniutes

How many miles does it last on a charge
10 if you drive it hard 20 if your cruising
Idk if I missed it, but what batteries are younusinng to power it? Looked like you had a whole bank of cells next to you...
A123 systems ANR26650m1-b cells in a 24s8p configuration.
