ATTENTION: For LiPo batteries it is absolutely necessary to use LiPo chargers with a built-in balancer. Lithium polymer batteries are electrically and thermally sensitive: overcharging, deep discharging, currents that are too high, operation at temperatures that are too high (greater than 60 °C) or too low (less than 0 °C) and storage in a discharged state damage or destroy the cells in most cases cases. Only use weapons with S-AEG that are also specified as LiPo ready.
