Extremely safe and stable chemistry: PCB and/or BMS built inside to balance protect the battery.
Long life-cycle: Can be circularly used, best can up to 2000 times recycles, 8 times of Lead acid battery.
Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.
Good performance at high temperature and high temperature resistance
Low self-discharge rate, less than 3% monthly.
No memory effects and highly efficient charge.
Environment friendly: Clean and Green energy poses no pollution on our environment.

3. Deep cycle lithium battery 48V 25Ah Safety Test

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	≤20mΩ		@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%	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.
