3. It is possible that the instrument is flooded, and the lighter can ride in the sun, and the heavier can change the instrument;

4. Check whether the speed regulating plug is connected reliably. 3 wires, the 4.2V (generally red) and signal wire (generally green) of the rotary handle can also be directly shorted, and the motor should be rotated after short-circuiting.

Controller is the core component of electric vehicle energy management and various control signal processing.
