Usage and Safety Precautions
Charger: Only use a LiPo balance charger to charge this battery.
Charging Safety: Always use a fire-retardant charging bag and never leave the battery unattended during charging.
Voltage Monitoring: The minimum cell voltage is 3.3V, and the fully charged voltage is 4.2V per cell maximum.
Condition Check: Stop using the battery immediately if its temperature exceeds 70°C or if the cells start to swell and expand.
Compatibility: 11.1V LiPo batteries should only be used in airsoft replicas that are specifically rated for them, as the high voltage can cause damage to standard (stock) internal components.
