Safety & Usage Warnings
Lithium Polymer (LiPo) batteries require specific handling and charging procedures to be used safely. 
Charger: Use a LiPo balance battery charger only.
Charging Location: Always use a fire-retardant charging bag and never leave the battery unattended during charging.
Voltage Monitoring: Always check cell voltages before and after charging. The minimum safe cell voltage is 3.3V, and the fully charged maximum is 4.20V per cell.
Damage/Overheating: Stop using the battery immediately if its temperature exceeds 70°C or if the cells swell and expand. Failure to comply may result in fire or explosion.
Compatibility: 11.1V LiPo batteries can cause damage (pre-engagement) in AEGs that are not designed to handle the higher voltage, so ensure your airsoft gun is compatible before use.
