Note 1: The successful start of the drill requires four 10C-20C power battery or Eight 5C-10C power battery(ordinary 18650 can not start the drill!!).
Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
Note 3: When the load of the brush motor is used, try to connect a non-polar (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.Only the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
