Main function:
Overcharge protection, over-discharge protection function, short circuit protection function, over current protection function, balance.
Important Cautions:
- Strictly according to the diagram wiring - do not make short circuit.
- After the wire is connected, it needs to charge the batteries first, then have output.
- When the battery is connected in series with 5 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 bad battery.
- It will be better if the capacity of the battery's internal resistance is closer.
