Nice! If you don't want them too fast you could always wire up a 36v setup using the factory motor. They won't last forever but my buddy has one that ran 36v on a stock controller and was a bit more fun for his kids. If it's for you, go for the gusto and do the 80v/3k Watts 🚀
@@DadModsMedia Yeah I'm digging into the potential now. As it sits my 8 year old has experienced a power wheels and my Jeep in 4low on some bunny trails so I think this at 12-15 mph will be a great step for him. Once we get the first one up and running we'll work on the second and see if little brother wants to tag along...if not we'll mod that one for some more speed!
@@geekytechycool very nice! Look into Kelly controllers when you're ready to step up the speed. They aren't cheap compared to the chinese stuff but they are worth the money.
@@geekytechycool any time! These little karts are ridiculously fun, I'm sure your kids will love em. In fact you should probably pick one up for yourself and do the big boy swap like mine 😆
You have good content, split your videos into like 15 min series and upload them every week or something. It will give you more clicks and exposure that way.
Thanks for the kind words! I chose to keep this one to a single video because the channel leans much heavier on the 1950 Ford and Camaro track car videos. Decided to do this so the subscribers of those builds aren't left waiting through 4 or 5 videos on the kart.
Hi Dad Mods, I love this video and we are using it to do the same project. I am wondering if you had to switch the gear on the new motor to accommodate the existing chain. The gear on our new 72V motor is bigger than the gear on the 24V motor, so it doesn't fit the chain. We tried putting the old motor gear on the new motor, but it doesn't fit. Just wondering if you ran into this issue? Thanks!
Yes I did actually have to install a different sprocket. Sorry, I just realized I did not have a link in the description for it. Here's the sprocket I puchased: amzn.to/3RmIeqB
Hi, I am planning on doing this build with 4 Dewalt 20V batteries (because I have dewalt tools). 20vx4 is 80V and this motor is 72V. Do you think this is a problem? I noticed you said 80V maxed in your description.
Hey David, so yeah these Makita batteries at full charge are basically 20v. So when everything is fresh this motor is tolerating 80v for a little while. My understanding is motors will tolerate a little bit of overclocking but it does reduce the life of the motor some. And these are cheap Chinese motors so who knows but so far mine has held up fine to all the screwing around we've done.
Great chassis... Just wanted to comment on the controller and battery choice. They are both really bad in terms of performance. Worked with a ton of them. That setup won't pull diddly for amps, and it will hurt the bats with 4 in series like that. Also that controller's input for the TPS is suuuper bad. Its like an on/off switch... They also have a soft start that limits initial accel. So you have very little throttle control and poor accel with that controller, coupled with really bad bats. Not that its not enough for a fun and a drift kart, don't get me wrong. But you could get a Kelly KBS-x controller that's the size of a cigarette pack that would be 10x better for about $120. And if you want to continue running drill bats (i don't recommend) At least run another set of 4 in parallel. Personally I'd get LIPO RC hobby bats. I used them on alot of builds. Then you could put some real tires on the back and have a super surprising go-kart as well.
Hey Adam, thanks for having a watch. So the rationale behind the component choices and power source of this project is more about fun per $$ than maximum performance. Almost every household has cordless drills and most of them hover around the 18v or higher range making the power source and ease of entry for someone very low. This is also a drift kart, so for it's intended purpose the setup I have is already overkill and honestly a little sketchy at max power, in the end all you really want to do is get up to speed and spin the tires for all the laughs. I can't imagine running a controller/battery setup that provides even more speed/power. As is, we've seen a Razor Go Kart (rubber tires) with this exact setup pull wheelies with me on it and the owner hit almost 40mph. Not sure I want more from such a twitchy little chassis. I appreciate your feedback though, I may need to ask you some questions when it comes time to build my next electric project. You clearly know your stuff. Do you post any of your builds somewhere?
@@DadModsMedia Completely get that. Hope it didn't come off as criticism. Ive built a few drift toys and throttle control is pretty helpful and improved the experience. Kelly controllers are relatively cheap as well adn perform 10x better. Though as you say, I'm not sure it matters much with a 3" diameter hard wheel or what ever those are. The issue with most small tool bats is you end up pulling too many amps through them. This kills the battery life quick, or destroys them all together. Which is why you generally run another set or more In parallel to you can keep the amperage draw within reason per pack. No real instructional vids. But I believe my channel has a few clips of the 120v razor I did with tool bats. Ran 3 in parallel to keep amp draw reasonable. Happy to help with any questions ruclips.net/video/po3Rqtk2z64/видео.html
No not at all man, and if it is criticism it's definitely constructive. So no worries at all. Looking at that video you linked, 120 volts on that MX looks wild. How was it to ride?
@@DadModsMedia Was great. As far as I know its still the record holder for 0-30 times on a razor with the 1020 style motors. 2.8 seconds on a draggy. And I'm not light at 200ish. Topped out at 47 with factory gearing. Went 55 on 134v worth of lipo on factory gearing as well. Def turning some nutty rpm. Also have a little pink pocket mod razor w 88v worth of lipo that does 43 and is a wheelie machine. I use them as pit bikes at the drag strips. Destroys most of the mild gas minibikes out there. Half the weight... none of the mess or noise.
Ha, same here. I built a kart that you sit on a cooler a few years back for cruising the pits as well. My next electric build will be something for that precise reason as well. Now, are you just stacking LIPOs then or actually splitting the packs and making your own? How are you handling the battery side cuz that seems to be the real challenge, especially if you're trying to watch costs.

Just picked up a couple of these karts last weekend. Working to get them driving again, love seeing the potential here.

Great detailed video. Have 2 collecting dust in the garage. May just have get one of these kits and have some fun
Believe me, it's so worth it. These silly things are so fun when you increase voltage and run a larger motor.
Glad you enjoyed the video!
It's 350 watts I got 1, I'm watching your videos trying to learn how to upgrade it.
Super cool
Thanks!
You should do a goped build!!! Trust me! Gsr46 or trail ripper or TR quad or goquad
Not familiar with those. I'll have to check our local marketplace listings 👊

@@DadModsMedia Awesome! Thank you for getting back so quickly. Got it ordered! We are super pumped on getting this project together.
Happy to help! You're going to have a blast when it's done. Just make sure your brake is working well before you start ripping 😆
@@DadModsMedia Definitely will check that brake. Thank you again!

OOO solder connecting all the batteries. fancy. Didn't want to just do twisties eh?
Yeah, I went ALL-OUT with this one, solder an all haha

Broooo. This thing looks slow AF lol 3k for THAT? ur kidding right?
You're doing way too much for something that won't get much use. Cutting it up so it didn't look weird!!??? Lol n smh
