Battlife Guard 3S Battery Protection Device (PBS2561)

Battlife Guard is a compact 3S LiPo battery protection device designed to extend pack life by automatically discharging a fully charged battery to a safe storage voltage when it’s left idle. It plugs into the battery’s discharge lead and monitors the pack voltage; if the voltage is above the safe threshold, it discharges the pack gradually over several hours, with an LED indicator showing that discharge is in progress. When the storage voltage is reached, the unit switches off and draws no further current, leaving the battery ready for long-term storage.

Designed for 3S LiPo packs, it does not use the balance lead and can remain connected after the discharge completes. For non-compatible battery configurations, a suitable converter may be required.
