I am hoping someone here can help point me the right direction.
I recently acquired a kid-size electric kart. I plan to start a build thread soon. It has a massive "1hp"-24v-42amp continuous Ohio Motor on it. Manufacturer data allows 550+ peak amps.
I dont need that much amperage... but 300 peak, 100 continuous would be nice. Something similar to a 12fet Lyen controller... except its brushed, so while that lyen brushless controller has 4 FETs for each phase, I only have one phase... so if you shoved all 12 FETs into PWM for one phase, it would be perfect.
so my thought was.. there would be a 12fet brushed controller like lyens somewhere.
I cant find it.
I found the "YK43B controller". It has 12FETs and people rave about it with kids toys.. but there is no current limiting at all. No cutouts. nothing more than power in, power out, and throttle.
The other options seem to be golf cart controllers (HUGE in size) or small EV-car controllers (expensive, and large).
The YK43B controller was only $30.. so I have one on the way.. and it will be fine for myself to test... but I can not let kids ride it with it. No current limiting. no brake cutoff.. not programmable. a kid holds the brake and throttle.. it would melt something. kid hits the throttle, it will go too fast. no way to dial it back... and last, I plan on running used EV lithium, so I want some kind of current limiting.
So... where can I find a 24-100 volt DC controller that is 100a continuous, 300-ish amps peak, with programmable amp limits? Im flexible on the voltage... but if it cant go as low as 24, it would have to have a speed limiter too.
