Power Queen 12V 10A LiFePO4 Battery Charger 14.6VThis Power Queen 14.6V 10A LiFePO4 battery charger is specifically designed for 12.8V LiFePO4 batteries using a two-stage constant current/constant voltage charging algorithm. The charger features smart LED indicators and a pre-charge function that activates batteries reading down to 0V. With a constant current of 10A and constant voltage around 14.6V, it can fully charge a 12V 50Ah LiFePO4 battery in approximately 5 hours. Multiple protection features include over-temperature, output short-circuit, reverse polarity, and output over-voltage protection. The charger is constructed from aluminum alloy with surface oxidation treatment and includes a built-in cooling fan.MPN14.6V10AItemweight3.20 poundsProductdimensions8.1 x 2.5 x 3.5 inchesPartnumber14.
