    Bafang ultra upgrade to 2500watt

    Hi,

    I want made homologated e-bikes that drive 60 - 70 km/u or 45 miles.

    Therefore I use the Bafang ultra drive. These motor can 2500watt but is 1000 watt.

    I need another controller or hack the controller that he can 50A.

    Luna have these controller but don't give info or I can't buy it. Do somebody know how they do it.

    Is it only software or another controller?

    I think maybe I can If I don't find how to change that, maybe E.R.T. 12 MOSFET 3000W Sinewave Controller can work?

    Then the heat of the controller don't heat the motor.

    Better so, only more cables.

    Anybody suggestions?

    Thanks
Working...
