Attentions：
1. Please allow tiny size deviations due to human measurement.
2. This item is an enhanced version BMS PCB without any equalized charging.
3. The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery(ordinary 18650 can not start the drill!!).
4. Strictly according to wiring guide 0V, 4.2V, 8.4V, 12.6V, do not touch any components on the board while soldering the wire to avoid short circuit.
5. Do not mix good batteries with bad ones.
6. The closer the internal resistance of the three battery capacities is the better.
7. When charging the battery, the “430” resistor heat is normal, indicating that the equalization circuit is working; if the “430” resistor is also hot in the uncharged state, please check if the wrong line is connected.
8. When connecting 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are different, please charge each battery group individually and reconnect it in series

Package Included
1 x 3S 40A Protection Board
