Crazy Cart 48v Controller & Charger Setup Guide

[@jthetunes1]

Dude I've watched every video you've uploaded and you've saved me so much time and money, huge thanks! Scored a cart on market place for 50 bucks and I'm doing everything you've done minus the motor and I'm using two 24v kobalt drill batteries to make 48v so I can have a bunch charging and just swap em out. One thing I'm surprised I haven't seen anyone do yet is completely swap the seat out. I like the pad you did on yours

[@TheCrazyCartModChannel]

Someone told me you can get a tractor seat from somewhere that swaps. but I totally forgot about that. I would love to find a way to put some compression springs under it to soften the ride even more. That is awesome that you've got one for THAT cheap!!! hell yeah! I am so happy to have helped you man. Just be careful to keep an eye out for your motor temps. The lithium power delivery is on another level for sure. take a look into the flipsky 7070 on the google doc, I'm going to be doing that mod next

[@jthetunes1]

Dude I couldn't believe it either. And I caught it when it was just listed. By the time I went to go pick it up about an hour later the guy was like "man I got an awful crazy amount of messages about this thing" 😂 I almost felt bad but he only wanted 50. Definitely going to check out the flipsky 7070. Is it something to bring the temp on the motor down? And I'm definitely going to end up retrofitting a different seat just for fun/comfort.

[@TheCrazyCartModChannel]

@@jthetunes1 the 7070 is a brushless motor. It's like 2000w and programmable. That's what I'm upgrading to next. It's on the parts list. Sorry I didn't respond sooner I didn't get this notification.

Bro you literally saved me like $100 I thought I ordered the wrong thing and was about to buy one from taxi garage. Thanks so much!

[@TheCrazyCartModChannel]

@@m-a-d-mike if you haven't bought the caster upgrade yet, hold up. I have an awesome video I'm shooting this weekend on a much cheaper, rebuild-able option. Look at my community post for pics.

[@Basketballclips-y3i]

Is there a plug on the 48v controller that you can connect a battery monitor to?

[@TheCrazyCartModChannel]

@@Basketballclips-y3iyes, it's covered in my videos.

[@mackskroll15]

How did you connect the wires from the battery monitor indicator to the controller? I noticed that when I stuck the red and black wires into the white cap thing it turns on. So how do I keep these connected?

[@TheCrazyCartModChannel]

@@mackskroll15 there's a connector called indicator. I mention it in either this the video or my other controller video. You just splice that up to the battery monitor and it turns on when you turn on the controller

[@m-a-d-mike]

I got a question for you. How big of battery would you use with this controller? Like what’s the max you would use to get the most out of it in terms of speed?

[@TheCrazyCartModChannel]

@@m-a-d-mike it's a 48v controller, so I'd stick to 48v. I have no idea if it can handle 60v, but maybe. I wouldn't want to blow the stock motor though. In terms of amps (Ah) my setup is 20 right now. There's a calculator that turns that into watts (I thinks amps x volts = watts?) And the controller claims to handle 1000 watts. So theoretically I'm pushing out 960 ways already. They do make more capable controllers but I haven't looked into that, as my goal was as cheap as possible for the most fun. My next upgrade though I think will be a lithium phosphate battery, but that'll have to wait until I feel like the money is worth it. I'm just trying to help people understand that Taxi garage is not the only option.

[@Kwaason]

Hey I have the normal crazy cart DLX and I bought 1 extra 12v battery and a 36V controller and charger (I bought the ones you recommended on your website). I was just wondering what you have to do differently with that setup compared to this one. For example do you have to do that whole weird charger plug in thing or no? I just want to be prepared before I work on my crazy cart because I don’t want anything to go wrong.

[@TheCrazyCartModChannel]

@@Kwaason it's been so long and all my carts are 48v now. I honestly don't remember... I'm really sorry

[@Kwaason]

It’s okay but me and my dad put everything on and it was working well until I went to charge it. When I plugged it in the charging port made sparks. The extension cord I plugged it into wasn’t even on. My dad unplugged the battery from the controller and it didn’t make sparks anymore. My dad says that he thinks it sending power from the batteries to the charging port.

[@Kwaason]

Nevermind me and my dad found out that the problem was that the red and black wires needed to be swapped

[@TheCrazyCartModChannel]

@Kwaason that is fantastic. I'm really happy that you found a solution

[@TheCrazyCartModChannel]

@@Kwaason Yeah, it sounds like that. hopefully you didn't kill the controller!

[@rogerramirez3938]

So you can put a 48v controller even with the stock 24v motor? Thanks

[@TheCrazyCartModChannel]

please refer to the parts list and FAQ

[@JokingEagle1328]

Hey, so I bought a cart with my dad and he followed all of these steps and helped me make my cart go 20 mph. It was working perfectly for about a week until one day we decided to take it to the park. we put it in my dad's truck bed and when we took it out, we set it on the pavement and turned it on. As soon as I turned it on, it started making this weird noise and it started slowly driving itself. When I got on it, I started moving, but it was accelerating very slowly and the max speed was probably like 15 mph. I kept riding and accidently crashed at like 10 mph. the cart didn't flip, all that happened was that I slid off to the side. when I got back on, it didn't move, so I had to walk it back to my dad's truck. I rode it again at home to see if it was really broken. I rode onto the street and it was accelerating slowly again. I just tried again today and it didn't move at all. I would like help or any recommendations that you would give me.

[@JokingEagle1328]

I just talked to my dad after reading @evan.picture 's comment and realized that Im pretty sure thats what happened to me too.

[@TheCrazyCartModChannel]

@@JokingEagle1328 check that the wires that hook up to the on-off switch are actually connected. They're very tiny and the connection might be bad where you splice them. It could have been intermittent and then totally separated but not visually once you had your accident. Also the controller could just be bad. If it started moving by itself though there may be something going on with the pedal, see if you can clean that out or blow it and make sure it's dry. There's a lot of different things that could be the culprit here. I'm sorry that you're having problems

[@JokingEagle1328]

@@TheCrazyCartModChannel ok thanks for the fast response and feedback, my dad said we will buy another controller

[@TheCrazyCartModChannel]

@@JokingEagle1328 I would check what I said first. you may not need to! it can be as simple as a loose connection

[@JokingEagle1328]

@@TheCrazyCartModChannel ok sounds good

[@officialkal4]

Since I bought a battery with a charger and a charge port does that mean I dont have to make a custom charger connector

[@TheCrazyCartModChannel]

I thought I responded to this man sorry. All you have to do is apply some critical thought to the situation. If the goal is to have a charged battery and you bought the entire system that's set up for it to just plug right in, would it make sense to cut anything? Of course not right? As the saying goes, "Don't fix it if it ain't broken."

[@CBANZFN]

What battery and charger did you buy? Cuz im not tryna do this connector stuff

[@chazdoodle120]

is there a reason to not connect the charger port connector from the controller into the charging port

[@TheCrazyCartModChannel]

From what I read the other day, it will only work with the power button of the cart on. I did not know that when I made this video, so I guess you could wire it up to the stock charger port, but it will only charge in the on position. but I have not tried that.

[@chazdoodle120]

@@TheCrazyCartModChannelmaybe if there is a connection from the port to the switch?

[@TheCrazyCartModChannel]

@@chazdoodle120 I don't quite understand what you're saying. I think port and switch are basically synonyms in this situation. The reality is there is the connection from the controller and there is the charging port that you would splice it into. . If the controller has to have the on switch activated to work, that means whatever is happening is taking place inside of the controller, not outside of it to get it to work. Adding a connection on the outside wouldn't do anything. At least that's the best way I can look at it. Either way you're free to try it if you want of course

[@chazdoodle120]

@@TheCrazyCartModChannelyes, i’m saying could you splice the positive charge and the positive switch together to where it’s only on when either the switch is on, or its charging

[@TheCrazyCartModChannel]

@@chazdoodle120 I want to be careful in case you're meaning something but using the wrong words. There is no positive/negative to the on/off switch. It's just a break in the line on one side of the current that is either opened or closed. You wouldn't be able to have what you're asking for because the switch would still either close or open the connection. If you're suggesting to hook up both the stitch and the positive/negative of the charging to the charger port, then only plugging something in would turn it on (because it's completing the circuit) The problem with that is, you would be be sending current into a part of the controller the is not meant to have two different polarities. If the controllers on off switch were also the charging wires, then you could do it. You could just insert a cut off end of a charging cable with the wires jumped together. It would essentially be like a key. And then to charge it you insert the real charging cable. But you can't do it the way you're suggesting because your trying to wire in parallel two different things, one with polarity, and one that just completes a circuit. That would probably just short out the wires once you plugged in a charger. Do you understand?

[@Nomate368]

I recently bought this controller and one of the plugs says (sport) i cant find anything about it online or in diagrams of the product. Would you know?

[@TheCrazyCartModChannel]

@@Nomate368 I have jumped it while the throttle was pressed and there was no difference in speed at all so I ditched it. There's actually a comment on this video somewhere, but thank you and I'll add that to the FAQ

[@TheCrazyCartModChannel]

@@Nomate368 you know what though, it may not have increased top speed freewheeling, but maybe allows more amps through, which would increase acceleration. I have another controller I need to mod so I'll test that and see if anything happens. Thank you for bringing it back into my attention.

[@Nomate368]

@@TheCrazyCartModChannel my crazy kart is finished and i left the sport mode plug out. Ill join the wires together or put power to them to see if anything happens

@Nomate368 putting power to them might kill the controller, but thanks for letting me know. I jumped them last night and the cart actually seemed slower to me but it was a long day and I was really tired and annoyed. I'll test again today.

[@officialkal4]

Can I use the wire connectors where there a soldering point in the middle and you use a heat gun to solder them together.

[@TheCrazyCartModChannel]

Your question is a little unclear to me, but I don't think a heat gun would solder anything. you'd need a soldering gun.

@@officialkal4 practice makes perfect. No worries, thank you for being conscious of it. I think that's more effort than a lot of people put into it. 👍

[@chazdoodle120]

could you use the indicator or any other spare as a plug for underglow or maybe a headlight

[@TheCrazyCartModChannel]

You know, that just might work. I hadn't even thought of that. Indicator gives the battery voltage, so i don't think you would want to use that, but perhaps the brake light plug might work. Test it for voltage and see. Nice thinking. I am using a portable battery bank putting out 5v, to a usb set of LEDS that converts it up to 12v.

[@chazdoodle120]

@ okay, also. i had a pair of these lipo batteries for another project and they were charging fine. i got another pair to make 48v for this project. now whenever i try to charge them with my 24v charger (sets of 2) they all just say “bad battery” while they all still discharge power. why is that

[@TheCrazyCartModChannel]

@@chazdoodle120 You're not the first person who's had this problem... I have no idea what the issue is. I would say return them and see if another pair work ok. Try them individually first though, it might just be one that's bad. keep me posted

Bro I feel you. I bought my cousin one and upgraded it all for him. showed him how to charge it, and he calls me and says he plugged the charger into the controller.. "I got you bro" LOL freaking bought him another new one and took it an hour and a half down to him again. trust me, I get it.

[@evan.picture]

@@TheCrazyCartModChannel got it working on 48v. she rips. the longboard rear wheels are soo nice too. that stock motor gets hot quickly though which sucks, deciding between waiting a week and getting brushedless 7070+ controller for ~$200 or buying a new 350w has your aftermarket 350w ever gotten too hot? granted its larger also, i would put a heatsink on it if i was confident it could allow for 40 minutes of straight ripping, but i doubt it would let me know your thoughts on a heatsink and a different 350w to manage heat sitting on stock sprokets and the top end is already scary. 47t gear coming real soon but the motor already gets hot on stock gearing so more torque wouldnt help let me know

[@officialkal4]

I just got my controller and im kinda confused on what cables i need to use vs the ones i dont need to use. And can i just cut the connectors from the old controller and just use heat connectors to connect them?

Can you overvolt a 36v controller with a 48v battery the same way you overvault a 24v controller with a 36v battery ? And would it still work better with a 250w motor or the 500w xl motor ?

[@TheCrazyCartModChannel]

@@EJDRIFTZ I had success over volting the 36 volt controller, but I wouldn't recommend it because it acted weird and it's only a couple bucks more for the 48 volt controller. As far as the motor is concerned you're always going to have better performance with a higher wattage motor.

[@TheCrazyCartModChannel]

@@EJDRIFTZ you need to define what "work better" means really. XL motor has more torque but will spin slower because it's not being overvolted to twice it's voltage like the 24v motor. It's going to be a trade off between longevity of the motor and cost as well. The question is: what are you wanting exactly?

When adding the 36v controller will I have to cut the charger and do that same thing ?

I dont know which one he used but he didn't have to do all of this. And also he didn't desolder as well. And with your battery video he didn't have to wire it in just plug it in like the speed controller. Unless he did those all off camera which would be strange for a tutorial.
