Bafang M400 G330 Motor controller (UART /CAN)

Bafang M400 G330 motor controller for replacement. There are two protocols for Bafang G330 controller, UART or CANbus; for CANbus motor, you will need to calibrate the motor after replacing the controller. UART protocol controller will have a "U" mark on the controller, it's EB-BUS connector  is with female connector and the display for the motor would be UART protocol with a 5 pin round connector.  If the display connector is with triangle connector, then it is with CAN protocol. The back of the display may also mark “CAN” . If you don't know how to identiy UART and CANbus motor, please email us. 

The Bafang M400 G330 controllers has several parameters, 36V 250W, 36V 350W, 43V 350W or 48V 350W controllers, please check your own motor before placing the order. By the way, If  your original M400 controller is 48V250W, please choose 48V 350W controller for your motor(Bafang has upgraded 250W 48V controller to be 350W 48V).
