Please Notice:

1. For the RC battery, only if the voltage and the plug match, then it will fit.
2. Please stop charging immediately when the cell voltage has been charged to 4.2v (Normal cell voltage is between 3.7v~4.2v).
3. To double make sure of safety, please have a check first whether the battery surface is alright when you get it and whether the voltage is normal before using.
4. If the new battery won’t hold a full charge or loss the charge very quickly in a short time, please use the Balance Charger to charge and recycle several times first.
