Main function:

Overcharge protection, over-discharge protection function, short circuit protection function, over current protection function, balance.

Notes:

  • Strictly according to the diagram wiring: 0V(B-) 3.7V(B1) 7.4V(B2) 11.1V(B3) 14.8(B+), Do not deliberately 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 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.
