3. Electrical Characteristics & Test Condition
@Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.

NO	Items	Criterion		Condition
1	Capacity	≥125Ah		Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the cutoff voltage. you can stop and define the Discharging current*time value (Ah) as battery capacity.
2	Cycle life (DOD%100)	≥2000cycle		Charge / CC(0.33C)/CV(14.6V); End current : 0.05C; Rest time : 1h; Discharge / CC(0.5C); End voltage : 8.0V; Repeat above process until discharge capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
3	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%
4	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. New function
It's available to add Bluetooth tool for monitoring battery feature from smart phone as following:

Battery pack voltage
Battery current draw
Battery state of charge
Battery state of discharge
Battery cycles
Battery temperature
Remaining capacity
Designed capacity
Full capacity
Series Number
Manufacturer name

5. Storage and Transportation

1) Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
2) Battery should be stayed in the ware house -20℃～35℃ where it’s dry, clean, shade, and well-ventilated.
3) The battery should be stored in 50% SOC during transportation.
4) The battery need to be charged every 6 months if out of use
5) Keep the battery against dropping, turning over and serious stacking during loading.
