Bafang CAN Bus Motor Controller CR X10B.350.FC 2.1 36V 15A 250W

Replacement CAN bus motor controller for Bafang e-bike drive systems. This controller is designed for 36V, 15A and 250W systems and has manufacturer part number CR X10B.350.FC 2.1.

Important: Bafang drive systems can use different communication protocols, controller versions and connector configurations. This product is a CAN bus controller and is not interchangeable with UART protocol controllers. Please check the manufacturer part number, electrical specifications and connectors of your original controller carefully before ordering.

Please note: despite the "350" in the manufacturer part number, this controller is specified for a 250W system.

Bafang CAN Bus Controller Compatibility

Bafang controllers can look very similar externally while using different communication protocols, firmware versions, electrical specifications and connectors. A visually similar controller is therefore not necessarily compatible with your e-bike.

The safest way to identify the correct replacement controller is to compare the complete manufacturer part number printed on the original controller.

This controller is identified by:

CR X10B.350.FC 2.1

If the part number on your original controller is different, please contact us before ordering so we can help check compatibility.

CAN Bus vs UART Bafang Controllers

Bafang e-bike systems are available with different communication protocols, including CAN bus and UART. Controllers designed for these systems use different electronics and should not be considered interchangeable simply because they have a similar shape or fit inside the same motor housing.

• CAN bus controller: communicates using the CAN protocol and may require system-specific configuration or calibration after installation.
• UART controller: uses the UART communication protocol and is not compatible with CAN bus electronics.

This product is a CAN bus version. It is not suitable as a direct replacement for a UART controller.

How to Check Compatibility Before Ordering

Before purchasing this Bafang controller, please compare it carefully with the controller currently installed in your e-bike.

Please verify the following:

• Your system uses the CAN bus communication protocol.
• Your system voltage is 36V.
• Your motor is rated at 250W.
• The required controller current is 15A.
• The manufacturer part number corresponds to CR X10B.350.FC 2.1.
• The controller connectors match your existing wiring.
• The motor and display are designed for the same CAN bus system.
• Any additional markings or version numbers on the original controller correspond to the replacement part.

We strongly recommend checking the complete manufacturer part number, electrical specifications and connector type before placing an order rather than relying only on the appearance of the controller.

Manufacturer Part Number

Bafang manufacturer part number:

CR X10B.350.FC 2.1

Comparing the complete part number with the markings on your original controller is one of the most reliable ways to confirm compatibility.

Installation and Configuration

CAN bus controllers may require system configuration, calibration or diagnostic procedures after replacement, depending on the Bafang drive system and e-bike configuration.

Installation and setup by a qualified e-bike technician with suitable Bafang diagnostic equipment is recommended where required.
