how to replace Bafang M420 /G332 Motor controller

[@АлександрМезей-п9и]

Kind de tell me please on the connectors of this motor? does it support the throttle stick, and brake sensors to cut off the motor? I have a motor with a UART connector, when the pedestrian assistance button is pressed, it works, but when the connecting rod shaft is twisted, it does not want to.

This motor may not support throttle; the torque sensor would be defective for your motor

Hi! Can you use a 48v 14a battery with a 48v 13a controller? I can only find 48v 13a controller on you website! Thank you for your help!

The battery current is OK as far as it is larger than the controller rated current; The controllers we have are the latest version from Bafang.

Can or Uart protocol M420

[@Greenbikekit]

UART and CAN is the same way to replace the controller, the only difference is CANbus motor needs calibration with besst tool
