3. Please strictly follow the wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B +), do not deliberately short circuit.
4. Please charge after connecting the line, then it will has output.
5. When connecting three groups of batteries, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. Discharge test, the voltage drops quickly when the group of battery time difference battery.
6. Please do not mix the battery and the poor battery together! 3 sets of battery capacity / resistance closer to the better! (Two good batteries +1 a poor battery use effect = 3 poor battery use effect).
The wiring is taken from B-
B- connected total negative
B1 connect the positive side of the battery
B + is soldered to the battery positive pole
P-welding line to charge and discharge the negative
P + solder the line to charge and discharge the positive pole.
