3. Electrical Characteristics & Test Condition

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

NO	Items	Criterion		Condition
1	Internal Impedance	≤40mΩ		Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument.
2	Capacity	≥58.8Ah		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 180 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
3	Short circuit protection	Automatically cutoff discharging when short circuit, and release after remove the lead.		Connect the positive and negative of this battery pack through a lead with the resistance less than 5mΩ.
4	MAX charge Current	50A		Charging with this current for more than 0.5h and the added temperature of battery pack less than 20℃.
5	MAX discharge Current	50A		Discharging with this current for more than 0.5h and the added temperature of battery pack less than 35℃.
6	Cycle life (DOD%100)	≥2000cycle		Discharge with the current of 0.5C 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.
7	Discharge Temperature Characteristics	-20℃	≥70%	At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage. Record the ratio between discharging & charging capacity.
		0℃	≥80%
		25℃	100%
		55℃	≥95%
8	Charge Retention ability	remain capacity≥90%		Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.

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.

Test item	Content	Criterion
Over charge	Over-charge protection for each cell	3.80±0.03V
	Over-charge release for each cell	3.60±0.05V
	Over-charge release method	Under the release voltage
Over discharge	Over-discharge protection for each cell	2.00±0.05V
	Over-discharge release for each cell	2.30±0.05V
	Over-discharge release method	Charging
Over current	Discharge over current protection	170~220A
	Protection delay time	0.5~1.5s
	Over current release method	Release after cutoff the load.
Over Temperature	Battery over temperature	Protection @65±5℃
Over Temperature	Battery over temperature	Release @50±5℃
