Hello, I am building an electric cart for my 6 year old son and need a little help with the electrical parts/ wiring etc. I already have a 250w 24v 11 tooth brush motor (MY1016) and 2 x 12volt 20amp deep cycle batteries and charger. The rest of the steel frame cart is built with most of its parts salvaged from on old kids quad bike.
I am guessing I would still need the following items:
-1 foot throttle (THR-90 or THR-91)
-1 speed controller box 250w 24v (SPD-24250A)
-1 key switch
- 1 relay ?
- 30 amp fuse ?
IS THERE ANYTHING ELSE I WOULD NEED????
The cart with batteries will weigh approximately 50 pounds and my son weighs 65 pounds. 115 pounds total. Will all this weight need a heavy duty speed control box? more batteries etc etc.
Ideally i do not want the cart to go any faster than 10mph. It has 10 inch wheels and a rear sprocket with 65 teeth. Can i put a speed limiter on the cart in the electrical system if it goes to fast? I guess i could simple build a stop to stop the foot throttle fully opening.
Any help would be greatly and hugely appreciated, as the electrical side of this project is not something that I excel in.
