[Specifically Designed For LiFePO4 Battery] Power Queen 14.6V 20A LiFePO4 lithium batteries smart charger is uniquely designed for 12V LiFePO4 battery, implementing the special 2-stage constant current/constant voltage (CC/CV) charge algorithm with smart LED indicators. This charger has a specific Pre-Charge function, which is designed to activate all types of BMS by allowing current into lithium batteries to read from down to 0V.

[High-efficiency Charging] With a constant current of 20A and a constant voltage of around 14.6V, it’s Ideal for LiFePO4 batteries 20 amp hours and above. It only needs 2.5 hours of fast charging time to fully charge a 12V 50Ah LiFePO4 battery compared with a 3 amps multi-charger which needs 17 hours to fully charge a 50Ah battery.

[Multiple Protection] Power Queen 14.6V 20A LiFePO4 lithium battery charger has multiple protection, such as over-temperature protection, output short-circuits protection, reverse polarity connection protection, and output over-voltage protection to prevent damage from faulty operation.

[Easy Operation & Visible Indicator] Connected and – alligator clips of the charger to the battery as to , - to -. Then plug in the input cable to the charger and connect it to the input power—intuitive LED indicators to provide visual charging state feedback and diagnostic information.

[Premium Quality] Our LiFePO4 lithium battery charger is made of aluminum alloy with surface oxidation treatment, high hardness, and anti-oxidation, and the built-in cooling fan keeps the charger itself cool. Heat dissipations protect your charger and battery. It’s safe to charge.
