u/Gold_Arrival77

I recently rebuilt my kids car. I re-wired it using relays (low power things like the the fwd/reverse swtch, pedal, etc are isolated from the motors and their big current draw.)

I also swapped out all 4 motors/gear boxes with 24V 775's.

My kid tried it last night and it absolutely screams (SUCCESS!) but the motors were sparking, so we stopped.

I calculated the current draw to be about 47amps, and since the yard is slightly rough terrain, I'm guessing it's more like 50-60amps.

How do I protect the motors?

I am considering current regulators, but don't have any experience. Anyone have suggestions?

Notes: each motor is 280watts on a 24v system
