Safety Notes

1. To ensure safety, please check and confirm Li-Po battery surface and voltage is normal before using.
2. If the new Li-Po battery won’t hold a full charge or loose charge very quickly in short time, then please use a Professional Li-po battery Charger to charge and recycle several times first. (See our Li-Po Balance charges from $95 upwards. 
3. For most Li-Po battery, the safest charge rate is 1C – 2C.
4. Never Over-charge above 4.2V per cell and Over-discharge below 3.2V per cell. (Normal cell voltage is between 3.7V~4.2V). 
5. When charging with a professional balance charger, always charge the battery 100-200mAh less than the amperage of the battery.  For example if the battery is 5000mah then charge at 4900mah.
6. Never charge Li-Po battery unattended.
7. If you are not using the battery for a while, please plug the battery off the car and leave it at the storage charge voltage which is 3.85v for each cell.
