Description: Features: 100% Brand New and High Quality Strictly according to the diagram wiring: 0V (B) 3.7V (B1)7.4V (B2)11.1V (B+), Do not deliberately short circuit. After the line is connected, need to charge 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 same, please fill in each set of batteries and then use. Do not mix the good battery and the battery. The capacity of the battery internal resistance is closer will be better. Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying.
