Minimum Capacity		10 Ah@ 0.2C	≥10Ah
Typical voltage		3.2V
Weight		288g±12g
Impendence		≤3mΩ	Less Than 3mΩ
Charge current (CC-CV)	Suggestion continue charge current	≤1C(10A)	0℃～45℃，Suggest the max charge current less than 1C. To Achieve the max. Service life. 0.2C（CC）to 3.65V, At 3.65V（CV）until the current ≤0.02C, then stop charge. (P.S: Large continue charge rate will reduction of the service life of the cell. Considering the high rate will lead to temperature rising, we are not suggest the battery pack work on high charge rate continue long time.)
	Max charge current	≤5C(50A)
	Cut off voltage	3.65V
Discharge	Max. continue discharge current	≤20C(200A)	-20℃~60℃ suggest the max. charge current less than 1C. To Achieve the max. Service life. 0.2C（CC）to 2.0V, stop discharge. (P.S: Large continue discharge rate will reduction of the service life of the cell. Considering the high rate will lead to temperature rising, we are not suggest the battery pack work on high discharge rate continue long time.)
