1	Charge cut-off voltage	3.65V	The capacity means the discharge capacity of the cell, which is measured with discharge current of 0.5C with 2.5V cut-off voltage after standard charge
2	Nominal voltage	3.2V
3	Discharge cut-off voltage	2.0V
4	Rated Capacity	50Ah @0.5C Discharge
5	Standard Charging method	0.5C CC(constant current)charge to 3.65V,then CV(constant voltage 3.65V)charge till charge current decline to ≤0.05C
6	Max charge current	1.0C
7	discharge current	1.0C(Continuous discharge current ) 2.0C (Instantaneous discharge current -10-60℃)
