Overcharge protection, over-discharge protection function, short circuit protection function, over current protection function, balance.
- Strictly according to the diagram wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B +), do not short!.
- After the wire is connected, it needs to charge the batteries first, then have output.
- When the battery is connected in series with 3 groups, please ensure that the voltage of each battery is the same. If not the same, please fill in each set of batteries and then use them.
- Do not mix the good battery and the battery.
- It will be better the capacity of the battery internal resistance is closer.
