Compatibility

Xiaomi Electric Scooter 4 Lite 2nd Gen

It is important to note that the Xiaomi 4 Lite 2nd Gen is not the same model as the first-generation Xiaomi 4 Lite. The controller’s connectors, electrical specifications, and software may differ, so it is recommended that you check the model and connectors of your existing control board before purchasing.

When might you need a Xiaomi 4 Lite controller?

The Xiaomi 4 Lite control board can be replaced if the scooter won’t turn on, no longer controls the motor, displays a control board-related error, or if the existing board has been damaged due to moisture, a short circuit, or other electrical system malfunctions.

However, these symptoms do not necessarily mean that the controller is the one that has failed. Before replacing the part, it is recommended to check the battery, motor, wires, connectors, and other related components.

Installing the Xiaomi 4 Lite Controller

It is recommended that you have experience repairing electric scooters before replacing the control board. Be sure to disconnect the battery before beginning work. Connections must be made according to the scooter’s original wiring diagram.

When replacing the control board on a Xiaomi 4 Lite, it is recommended that you mark or take a photo of the layout of all connections before removing the old control board.
