ExpertPower 12V 20A Smart Charger for LiFePO4 Batteries — 14.4V CC/CV, Cut-off 1.5-2.5A, for LiFePO4 batteries 40 amp hours and above

Charging specifications: 14.4V charging voltage | Charging current: 20A | Cut-off current: 1.5-2.5A. Recommended for LiFePO4 batteries 40 amp hours and above. Engineered for 12V LiFePO4 packs, this charger uses a two-stage constant current/constant voltage (2-stage CC/CV) charging algorithm and includes smart LED indicators to show status. While active it can reset all types of BMS by supplying current into batteries that read down to 0V, allowing recovery of deeply discharged cells. Designed to preserve cell health, the CC/CV charging method increases charge efficiency and helps extend the service life of LiFePO4 batteries — effective whether the battery has a BMS or not. Built for durability and thermal management, the unit features a unibody aluminum alloy housing plus a cooling fan so the exterior doubles as a heat sink and provides over-heating protection.
