3. Test conditions

Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.

Normal charge:Charge battery under CC(0.33C)/CV(43.8V) mode until over charge protection or the charge current reduce to 0.05C, and then rest for 1h.

4. Product Performance

NO.	Items	Criteria		Testing method
4.1	Rated Capacity	40Ah		Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.

4.3	Internal resistance	≤40mΩ		50% battery SOC state frequency of 1 KHZ ac resistance tester
4.5	Cycle life (DOD100%)	≥2000cycle		Discharge with the current of 0.33C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
4.6	Discharge Temperature Characteristics	-20℃	≥70%	At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage.
		-0℃	≥80%
		25℃	≥100%
		55℃	≥95%
4.7	Charge Retention ability	Residual capacity≥80%		Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.
