The first is that I plugged in the batteries separately so I can run on the main or backup baterie, but if it goes on the backup battery, the connector between the battery and the scooter gets hot and ruins. Does anyone know if the second additional battery directly powers the motor on the original scooter or recharges the original battery in the scooter?
The second problem is with the brake. Even if the control unit 2 has wires that are described as a brake, it will only disconnect the throttle when connected. Now I plan to build a contactor for motor braking, which reverses the winding and turns back on for braking time. Did somebody solve it here, or did someone get a brake on the control unit from Alliexperes? Thanks
