The Battlife Guard has been specifically designed for 2S and 3S LiIon and LiPo batteries. With this small connector, the lifespan of battery packs can be significantly extended with minimal effort. Lithium batteries age much faster when stored in a fully charged state for extended periods. The Battlife Guard is simply plugged into the battery connector, and the electronics detect whether the battery pack is above a certain voltage level. If the voltage exceeds the threshold that is harmful to the battery, the battery is gently brought down to a lower voltage level over several hours. The built-in LED indicates whether the battery is being discharged. The voltage level is set so that the battery can be stored for a long time without damage. The Battlife Guard can remain connected to the battery even after the discharge process - once the battery reaches its storage voltage, the Battlife Guard turns off and consumes no more power.

Features:
