This requires 3 15C-20C power batteries, or 6 10C-15C power batteries. Please follow the wiring according to the voltage or else it might cause a short circuit.

When the load of the brush motor is used, try to connect a non-polar capacitor (with stand voltage above 25 V, capacity 10 uF-100 uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.

The batteries are arranged as a series circuit. Please ensure that the voltage of each group of batteries are the same, or else please fill each battery separately and then use in series.

The Discharge test: Voltage will Drop faster is the battery being used in a group is poor/low on power.
