What to compare before ordering

Choose according to the exact scooter generation and its existing electrical connections. Controllers for the first-generation 4 Lite, the 4 Pro and other Xiaomi scooters can look similar. Appearance alone does not establish that they are interchangeable. This card is specifically for the 4 Lite (2nd Gen) version.

Compare the old unit’s housing, mounting position and connector arrangement with the gallery photographs. Wire colours can help you identify the harness, but colour alone is not a sufficient basis for making electrical connections. The function of each contact must also match.

Replacement and package contents

Disconnect the battery before replacing the controller. Installation is best carried out by someone familiar with electric scooter electronics. Route the wires so they cannot be trapped by the scooter body and make sure all connectors are properly seated.

A scooter that will not switch on, or a motor that does not run correctly, does not always have a faulty controller. Check the battery, contacts and wiring before replacing parts. One control unit is supplied; a dashboard, battery and indicator lights are not included.
