Package Contents:
1 x 4S 40A Li-ion Lithium Battery Protection Board
Note 1: The successful start of the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (the normal 18650 cannot start the drill!).
Note 2: strictly in accordance with the map wiring 0 V, 4.2 V, 8.4 V, 12.6 V, 16.8 V, do not intentionally short circuit.
Note 3: When using the brush motor load, try to connect a non-polar capacitor (withstand voltage above 25 V, CAPACITY 10 uF 100 uF) to the positive and negative terminals of the motor to avoid the reverse peak of the motor. Break the MOS tube.
Note 4: 4 groups of batteries in series, make sure that the voltage of each group of batteries, if not the same, complete each battery separately and use it in series. The discharge test, the battery voltage drops faster than the group is a poor battery.
