Note: For products that draw more than 3A of current, the battery’s discharge rate should be at least 3C to ensure optimal performance.
Precautions:
1. Please strictly follow the wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B ), do not deliberately short circuit.
2. Please charge after connecting the line, then it will have output.
3. 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.
4. 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).
