Just bought a Himiway cruiser (48 volts with 750 watt motor) and have been fine tuning some of the program settings. When I checked the controller over-current cut settings, it was set at 25 amps which seems a little high (1200 watts @ 48 volts), so I set it down to 15 amps which is the factory default. I did this thinking that if it was too high, it might be putting the controller and/or motor at risk. Then I began to think (always a mistake) that a battery fully charged is more than 48 volts and that this setting doesn't take into account current surges that might occur when accelerating. There must be a happy medium that protects the circuitry but doesn't result in a premature cutoff. Anybody have any experience with this?
