Product Description<br> Features:<br> 100% Brand New and High Quality<br> Strictly according to the diagram wiring: 0V(B )3.7V(B1)7.4V(B2)11.1V(B+), Do not deliberately short circuit.<br> After the line is connected, Need to charge first, then have output.<br> 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.<br> Do not mix the good battery and the battery.<br> The capacity of the battery internal resistance is closer will be better.<br> Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better.
