d8veh said:Your controller's power rating is pretty meaningless. My guess is that it's set to about 20amps, which is 800w through it. For other controllers, you can increase the current by up to 50%, and or feed it a higher voltage, both of which will make it pass more current. Most controllers' watt rating is related to its heat making and shedding ability, but yours is probably under-rated for legal reasons. That's if it has a rating written on it.Rim21 said:Hi All - new to this forum but am hoping that the technical minds of the many can help me solve the BH Emotion controller question - can a 250w controller be manipulated into giving a 350w output. Note also that I am self-teaching myself micro-controller programming which basically means that I am willing to give things a go but am no expert.
One solution is to installed Bafang Crank-drives 350w36v.
