Hey guys, I'm hoping you guys could help. In the interest of safety, I've downgraded from 74 volts to 37 volts (lithium polymer voltage). I've got a new controller which is the digital variable 36-72 volts controller and in addition have gotten the digital readout that measures amps, volts, etc.
The problem I'm having is that the digital controller has a tendency to power-down quite noticeably when 50 amps is surpassed which is quite easy to do. Even at max speed of 30ish mph, when I'm sitting upright with a jacket on, it's pulling about 50 amps due to wind resistance/slight uphills.
So, I need to raise the amperage capabilities. Now, the question is, can I simply solder more FETs to double the capacity or is there some other electronic circuitry that I need to play around with in order raise the amperage limits?
Would it be more cost effective just to buy a 200 amp bike controller? How do I go about finding an adapter for the hall sensors and throttle? Any help would be greatly appreciated.
