3. Electrical Characteristics & Test Condition

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

NO	Items	Criterion		Condition
3.1	Normal Capacity	300Ah		After Normal charge, discharge @0.33C current to the end of discharge voltage.
3.2	Internal Impedance	≤30mΩ		@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	Discharge temperature characteristic@0.33C	-20℃(6h)	≥70%	the percentage accord with criterion Capacity @specified temperature Capacity @ 25℃
		0℃(6h)	≥80%
		25℃(4h)	≥100%
		55℃(4h)	≥95%
3.6	Capacity retention rate	remain capacity ≥96%		After normal charge, store the battery @25±5℃ 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.
