Ok so I have a emad off road electric skateboard. Originally it is powered by 3 12v 10ah batteries wired together in series. To power a DC motor (model#MY8919) that's rated for 36v 28.4A 800w output. All controlled with a rc remote. Now after a lot of troubleshooting. I have come to the conclusion that something is wrong with the main control board. So I've decided to restructure the board so that it has a wired controller. What would be the best way to do do this? I was thinking of doing it kinda like a golf card would be done. With a solenoid and limit switch. But the DC motor is also equiped with what I think may be a breaking feature. Any advice and knowledge is appreciated.
