Continuous charging current (upper limit):20A
Applicable electric drill:electric drill with starting current below 80A and power below 135W.
Note
1. To start the electric drill successfully, you need 4 power batteries of 15C-20C, or 8 power batteries of 10C-15C (ordinary 18650 cannot start the electric drill!! !).
2. Wire 0V, 4.2V, 8.4V, 12.6V, 16.8V strictly according to the diagram, and do not intentionally short-circuit.
3. For loads with brushed motors, try to connect a non-polar capacitor in parallel with the positive and negative terminals of the motor (withstand voltage above 25V, capacity 10uF-100uF) to prevent the reverse peak voltage generated by the motor from interfering with the protection board or breakdown MOS tube.
4. When connecting 4 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are not the same, please charge each set of batteries separately and use them in series. . . During the discharge test, the battery with the faster voltage drop is a bad battery.
