Hey there sir Im about to puchase a kidzone bumper car bit would like your upgrade. Is there a way you can do it and i pay you? Please let me know @randofix
@@jovanyfernandez7917 as much as I would like to help, I do not offer that service. I assure you it's fairly easy to do, you just need the proper tools and motivation to get it done. Best of luck!
For most computer fans, they have 5 volt versions and 12 volt versions. Perhaps, it might make sense to have some fans that are the right voltage, to keep them from one day burning out, too. The larger fans often end up being cheaper & moving more air. There are also some proper clip-on heatsinks you can get, if you are concerned. You might want to feel the wiring, after running it for a while. It's possible that you might want some slightly heavier wiring - at least, to the motors. Finally, since that's a generic brand vehicle, they have 12 volt gearboxes, that you can swap out for the 6 volt ones. This will give you a bit more longevity, if the motors ever burn out. It's a good project & an informative video.
Thanks for all the recommendations! The fans were actually spares so if they burn up it won’t be a huge deal but I might look into beefier fans later on. Check out my 12V upgrade I did, which worked out really well and the motors and gearboxes hold up great. Eventually I want to do a 40V upgrade and that’s when everything you mentioned are really going to take effect. Glad you like the video and thanks for watching!
I've just put a 12v battery into my kids bumper car and ran fine. Put in a 18v drill battery and one of the capacitors blew, obviously. Now I'm looking to upgrade it as going back to 6v just isn't good enough now.
Dang! The circuit boards are terribly built and that is exactly why I did a complete rewire of the whole car. I know what you mean about the 6V, it's incredibly slow! I'm debating whether or not to make a full video of how to do a rewire. Let me know if that is something you want me to do or if you want to just figure it out yourself.
@randofix It would be a huge help if you did a video as there isn't much to go by on the Internet. I've ordered a new capacitor and will get it soldered during the week but my daughter isn't pleased that it has to go back to standard... for now.
@randofix No worries mate, I completely understand how it is. Got some new capacitors turned up today so I'll get them soldered in the meantime so then the kids can at least use it at a snails pace.
If using a voltage regulator on the upgraded board would there be any more reworking needed ? Would you consider a step by step video for those who are not 12 volt or electrical back round. My daughters motor blew on her factory set up so now I’m definitely going to be fixing but now that I’ve seen this I’ll definitely be upgrading. But want to go the most reliable route possible.
If you blew up the stock board and need to order a new 12V board, then a voltage regulator will be a must to not blow it up when applying 18+ V to the system. I have thought about doing a step by step video but might take me a while as RU-vid for me is definitely a small hobby outside of my IRL job. Good luck and keep the questions coming if you have any more!
I’m not 100% sure but I would imagine that it would function. Maybe not nearly as well because there would be components that are designed to receive 24V and you’re only bringing in 20V. If you try it, I’d be curious to hear about how it works!
Just got one of these for my son and he is absolutely not impressed with how slooooow this thing goes. If I were to buy the 12 v board and a new 12 volt battery, I would just have to swap out the parts. Correct? Or could I also do the battery converter and use only a 16 volt drill battery and include volt regulator and still avoid an entire rewire? Help would be much appreciated. I’m not very experienced when it comes to electronics. Thanks
Oh yeah, the stock 6V is insanely slow! So a 12V board should do just fine and I would recommend an adapter to allow for the 16V drill battery. Don't buy a stock 12V battery because they don't put out the same level of amps and you'll see a difference but not nearly as noticeable as the 16V. You do run the risk of blowing up the board if you give it straight 16V so installing a DC volt regulator and dial it down to 12V would be perfect. Hope that helps!
Loved the video and great work! It has inspired me to upgrade my 2-year-old's bumper car. Could you please suggest how I can perform a simple upgrade from 6V to 12V without rewiring?
Awesome and so glad you like it! If you're going to stick with 12V, I suggest getting the RX25 12V board (link in the video description, make sure it will match with your bumper car) and also buy a voltage regulator to dial it down to 12V or less. If you have a multimeter and are willing to do a bit of tweaking, the voltage regulator I have in the description is a great option. However, if you want to stick with something easy, I would go with this one amzn.to/3PYUldV to go from 20V to 12V 3A automatically. My only disclaimer here is that I have no idea what the boards are rated for in terms of amps and you might run the risk of blowing it up (unlikely at 3A but still a possibility). That is why I went with a full rewire, but I totally appreciate the reason for not going that route. Let me know if you have any other questions!
Thanks! Hard telling exactly how fast but I would guess 2-3 mph or as fast as a brisk walk. I recently upgraded the motors to 12V (check out the video) and that goes way faster. Depending on the weight of the rider, it can keep up with other kids on their bikes.
I have a few questions. 1) since your no longer using a controller board, I assume you no longer have the remote control feature? 2) is it a step down voltage reducer you used? 3) you basically wired the 2 control switches directly to power?- can you please explain how you wired it to work in this configuration?
1) Unfortunately, since I'm not using the controller board, the remote no longer works. It is possible to use a voltage stepdown from the 20V to 12V to make the board work without risk of breaking it, but I wanted to have more power than the remote functionality. 2) Yep! I used a DC voltage step down that works perfectly for not needing to adjust the voltage often. If you plan on adjusting the voltage frequently, for safety or preference, then others are certainly better. 3) As much as I like the controller boards, the rewire was almost a must for me and you are correct, I did do a full rewire of the circuit but it is actually a lot easier than you think. I overengineered the wiring but I wanted it to last. If you need help on DPDT wiring configurations, check out the link I'll place in the description since a link here in the comments won't work. Hope that helps and thanks for watching!
@@randofix Hey thanks alot. - This really helped me out with my kids 12v bumper car which I converted to use a 18v Bosch power tool battery. Also replaced the stock 380 motors to 550 40,000 rpm motors with heat sinks & cooling fans attached, added a new speed controller to replace the existing RX25 control board, low voltage battery cut out, lcd voltage display, and put in voltage step down regulator to power the lights, Bluetooth speaker, etc. The problem I was having: I had everything all hooked up to the stock Weelye RX 12V control board and it would run only for a few seconds then cut out, and after a few seconds it would restart again but repeat the same process cutting out. I’m pretty sure the board couldn’t handle the new motors, etc. After watching your video I decided to ditch out the control board and do a full wiring job. I’m almost done finally lol. Took me away from my wife and kids for a long time trying to figure this thing out but I’m glad I’m almost done. I really would love to use the remote control because this bumper car is my sons and he’s only 1.5 years old and he doesn’t know how to drive yet. He’s starting to press the accelerators but he’s not quite ready yet. My 4 year old daughter has her own bumper car so maybe she’ll just drive this monster fast modified bumper car and let my son sit on hers till he gets older . Anyways thanks again. I maybe posting a tutorial video as well but let me finish it all up and go from there.
Thats freaking awesome and love the fact that you're going for the full rewire. What I discovered about the boards were that they're good for stock batteries but are so poorly built that anything outside of the rated capability will most likely end in disaster. My stock board literally blew up to the point where it caused a fire the first time I put 20V through it (it was a 6V board) and the second board blew up too after running it for a while. I could tell it was struggling because they out a throttle on it too and those don't do too well after receiving a lot of power. My next step for my bumper car is to swap the 6V motors with 12V ones (same as in a power wheels) and the goal is to get the kids to throw up after spinning on it haha! Those step downs will really help you out in keeping the lights and speakers working well, so always good to incorporate those. As for the motors, you would not believe how resilient motors are and they can take a tremendous amount of power before they blow up, so you can have a direct wire link from the battery to motors. However, you really want to use the step down for everything else because LEDs don't do well when you venture out of their power range. Excited to see what you come up with and hit me up if you run into any snags!
I’m finally finished with all the upgrades. It’s extremely fast with the dual 12v motor upgrade. I’ll be installing a universal remote control system soon. Thanks again for the awesome video tutorial. It sure helped me out alot!
@@13ay13oy that's epic and I bet it is a monster with the 12V motors! I plan on doing an upgrade video to do the same thing you did. Installing a universal remote? Very curious how you would do that, let me know if you put out a tutorial video. So glad the video helped you out!
Nope, two things were considered. First, the bracket that holds the motors is perfectly sized to the 6V motors and second is that I wanted to use them up while they were still good. Once they burn up or gears strip, I’ll replace them with 12V gearbox motors for pure carnage. Future video plan 🤣
Stumble up on this video of your. I’m trying to do exactly what u did for the bumper car. I put in an 18v drill battery and fried the module. Your video seems pretty self explanatory but I’m not a tech guy at all so have no idea how to follow the step to your video. If there a easy way to explain it or possibly tell me what I have to order and u can help me step by step for dummies. Tia
Unfortunately, if you want to continue using the controller boards and a drill battery, you're most likely going to run into issues with the overvolts; unless you get a voltage step down module (amzn.to/3PoBN6Y). However, a rewire is the best option but certainly takes some effort and the purchasing of some extra parts and tools. If you chance doing a rewire, this diagram (i0.wp.com/www.vegoilguy.co.uk/_maingifs/dpdt_switch_steering.png?w%5Cu003d2000) is the BEST to mimic and works perfectly for how the bumper car works. Sorry if that isn't entirely helpful but hope it makes sense. I guess I need to do another video showing exactly how to do the rewire in detail since I blew right over it in this video.
