Hello guys.

 Am an RC modeler and been doing electronics. Last year, I was asked to repair China made electric bike. yung yun sa gitna ang motor sa rear wheel mizmo.Dalawang malaking batterya, 24V nga ata. Gamit ay BRUSHLESS MOTOR. mas efficient daw ang BL motor sa brushed motor. 90% vs 60% ata.

anyway, the higher the V the better for the ESC since current drops inversely for the same power. The IRFxx series can go 50 amps. I 4got the V tho.  Parallel sila, marami.

I built ESCs for small brushed motrs. Same principle naman for bigger loads, mas marami lang Mosfets. But you can drive as many as you want with a 100 ohm series resistor to each gate.  For reverse, do not use bridge na prone to burning. a huge rlay can reverse the polarity sa motor. Pwede nga maechanical reverser lang.
