UL approved LiFePO4 cells;Qualified BMS;Robust ABS case; Interchange with lead acid battery;LED status indicator;
This specification is applied to the LiFePO4 battery pack that manufactured by O’CELL Technology Co., Ltd. There is built-in smart PCM for over charge/discharge, over temperature protection. It owns RS485 interface for communication and LED status indicator.
Application: Automobile Starting battery.
Do not connect in series to more than 24V. Do not short-circuit. External fuse recommended.
Standard discharge(0.2C)after standard charge(0.2C)
Residual capacity is more than 60% of the rated capacity
1) Charge: CC @ 0.2C to 14.6V, then CV till current to 0.05C
2) Rest: 30min.
3) Discharge: 0.2C to 10.0V
Carry out 1500 cycles
Discharge cut-off voltage
≥ 8.8V (2.2V/cell)
Over-discharge protection release at 10.0V
Charging cut-off voltage
Over-charge protection release at 14.6V
Flame Retardant Plastic
0.2C constant current (CC) charge to 14.6V,then constant voltage (CV)14.6V charge till charge current decline to ≤0.05C
Charge time : Approx 7.0h
Constant current 0.2C
Cut-off voltage 10.0V
