So I have been building a 36 volt powerwheels escalade that I can run around at car shows and other places. I has a pretty nice stereo system, under lighting (as you can see in my avitar and the videos) and many other thing. I reinforced everything built an axle with hubs and breaks. I got an electric scooter from someone that was going to throw it away. I stripped off everything from it and used it on a barbie 4 wheeler powerwheels it did about 25 mph down hill witch was a real thrill an pink plastic wheels.
The controller fryed out on it so I used the engine in my escalade and put in a 48 volt controller it ran for about 3 min till the controller started smoking. I was told later that I can't use a 48 volt con with a 24 volt motor but 36V con it the max that will work.
I just got my 36V con put in today and it is so under power that the stock 12V set up is faster. Now I'm thinking that I should either go with a full 48V system or just get a good 36V 1000 amp motor. I would like to get some input on what you guys think. And if anyone has a full 48V setup or a good 36V 1000amp motor let me know. Oh and I am running GENESIS G12V16AH10EP batts but I need more so if anyone looking to sell some let me know.
Awesome!
Can I just check - did you use a 24v motor with a 48v controller, and if so how many of those 12v Genesis batteries have u got in series?
Ultimately the questions not regarding the 36v or 48v controller its really what batteries youve got behind it all.
Well when I ran it with the 48V con it had 2 Genesis batteries one old Odyssey battery and just a plane motorcycle batt in series with the 12V motor. With this 36V we first used one GENESIS G12V16AH10EP and 2 GENESIS NP12-12T 12V. 12AH and it would hardly move, so we grabbed 2 big car batts and hooked them with same effect.
You might want to check your gear ratio. Sounds to me like you have it geared too high.

I think the video of the Barbie Quad is hilarious! Quite amazing that the 12v motor didnt burn out after putting 48volts through it!
@Chas - doesnt sound like the gearing if its the stock gearing that works with 12v and was so fast with 48v?? It would be odd if the gearing was was not ok with a voltage in between? That controller must be limiting the Amps considerably.
If you look at the second video you will see the stock gearing has been removed when a new axle was used. I still believe the gearing is too high. If you look at the size of the sprocket compared to the diameter of the wheel it looks to be way too small. A sprocket about 50% larger would be more in line with gear ratios used on most scooters. A high gear ratio will cause too much current draw and almost not starting torque.
