3. Electrical Characteristics & Test Condition

Testing Conditions: Ambient Temperature: 25±5℃ (68℉~86℉); Huminity:45%~75%.

Normal charge:Charge battery under CC(0.33C)/CV(58.4V) mode until over charge protection or the charge current reduce to 0.05C, and then rest for 1h.

NO	Items	Criterion		Condition
3.1	Normal Capacity	100Ah		After Normal charge, discharge @0.33C current to the end of discharge voltage.
3.2	Internal Impedance	≤80mΩ		@50% SOC @1kHz AC internal resistance test instrument.
3.3	Short circuit protection	Auto cutoff load when short circuit		Connect the positive and negative of this battery pack through a lead with 0.1Ω resistance.
3.4	Cycle life @DOD100%	≥2000 cycles		After Normal charge,discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.
3.5	@0.33C Discharge temperature characteristic@0.33C	-20℃ (-4℉)	≥70%	Capacity @specified temperature Capacity @ 25℃ (77℉)
		0℃ (32℉)	≥80%
		25℃ (77℉)	≥100%
		55℃ (131℉)	≥95%
3.6	Capacity retention rate	remain capacity ≥96%		After normal charge, store the battery @25±5℃ (68℉~86℉) for 28days, then discharge capacity @0.33C,the retention capacity accord with criterion.

4. Circuit Protection

The batteries are supplied with a LiFePO4 Battery Management System (BMS)that can monitor and optimized each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge, short circuit. Overall, the BMS helps to ensure safe and accurate running.
