Safety Notes
- Before using it, please fully charge it with a specific LiPo balance charger.
- If the new LiPo battery won’t hold a full charge or loss the charge very quickly in a short time, please use a professional lipo battery Charger to charge and recycle several times first. For most LiPo batteries, the safest charge rate is 1C.
- The charging temperature must range from 15-35 Celsius, reverse charging is prohibited.
- The voltage difference between any two cells should be in 0.03V, or a charge is advised to balance the voltages before usage.
- NEVER overcharge or Over-discharge lipo battery. Never charge above 4.2V per cell and discharge below 3.0V per cell. (Normal cell voltage is between 3.7V~4.2V).
- Do store battery at a place with low humidity and free from corrosive gas within the temperature ranged from -20 Celsius to +40 Celsius.
- Under any circumstances, disassembly of the battery is prohibited.
