Specially designed for Electripet Technology controllers, it can only connect to Bluetooth with the Electripet name. This device can read real-time parameters and alarm information from the motor controller. It allows users to freely adjust the power and speed of riding modes, enable or disable kinetic energy recovery, and the self-learning function of the motor only needs to be operated when replacing the motor or motor encoder. During self-learning, ensure that the wiring is correct and the tire is off the ground.
