Summary : 1.1 Name: USB Charger with PW4000 Chip for Charging Two 7.2V LiFePO4 Batteries at 5V-12V2A1.2 Application: Convenient charging device, etc.1.3 Battery pack: 6.4V LiFePO4 battery pack, two series connection and parallel connectionavailable, fully charged at 7.2V1.4 Input voltage: 5V-12V (charging indicator on when charging, fully charged indicator onwhen fully charged, flashing when no battery is connected). By changing the value of R5, itcan be changed to a tricking fast charging voltage of 9V, 15V, or 20V (please refer to thePW6603 specification for resistor values). By removing R11, R12, C9, PW6603, and the USB1interface, it can be directly powered by DC input of 5V-20V for normal charging of thebattery.1.5 Max charging current: 2A
