AC/DC adapters 14.6V 12A 4 cell charger for 12V LiFePO4 battery pack

a. The charger integrates power factor correction (PFC), it can avoid the impact of high current and can't produce pollution on the grid.

b. Efficiency>87% ,Power Factor>0.97 for charger with 120V-240V input, or >0.7 for charger with 120V/230V input.

c. With MCU controller, CC+CV(H)+CV(L) 3-stages charge method.

Protection:
1. The charger's internal relay makes  the output voltage is less than 5.5V with no-load, when the output is connected to a battery, the output voltage of charger is normal.
2. Short circuit protection: when the output of charger is shorted, the charger will close output automatically without any damage.
3. Reverse polarity protection: when the output is connected to a battery reversely, the charger will close output automatically without any damage.
4. Overheating protection: the internal temperature exceeds 80 ℃, the charger will close output automatically.
