4. BMS management system of 12V 7.5Ah 18650 battery pack
The LiFePO4 BMS provides protections for the 12.8V 7.5Ah 18650 battery pack. It provides protection functions of over current protection, over charge protection, over discharge protection, short circuit protection, over load protection and overheating protection etc.
Over current protection: The BMS will cut-off protection circuit if it is over current.
Overload protection: When output power or start power of device is too large, BMS automatically turn off the device. You need to turn off the switch, and then turn on the switch to make the product recover to normal.
Overheating protection: When internal temperature is over 149℉ or 65℃, BMS automatically turn off the device. You need to turn off the switch, and then turn on the switch to make the product recover to normal.
5. Standard charge Characteristics of LiFePO4 battery Pack
The "Standard Charge" means charging with constant current 0.2C to3.65V, then charging with constant voltage 3.65V to 0.01C under 20±5℃, charging time will not more than 8h.) (Use Lithium-ion battery charger, which with an accuracy ±0.05V.)
