So this is my homemade electric kart of many uses! running on a 24v system with two separate 24v motor controllers hooked up in parallel that then power an axle each with two motors wired in parallel as well. Each 24v 280w motor has a 30a fuse in case of shorting, and a larger 80a fuse protects the whole system in place before the motor controllers. controllers are 100a 24v fan cooled with forward and reverse built in with variable throttle. The frame is built from angle iron mostly with a few other bits for suspension and steering. Wheels are from a rotavator i believe but had to be modified to work.
any questions fire away!
