    Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

    Bafang Ultra mid drive running on 52v?

    Bafang Ultra mid drive running on 52v?

    The capacitors on the Bafang Ultra Controller are rated 63 Volts, so i do run mine on a 52 volt battery, wich has 58.8 volts when fully charged. Lets assume your controller settings are at 30 amps: 30a x 42v = 1260 watts 30a x 52v = 1560 watts So yes, performance improves :) I dont get your...
