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 ≥73.5Ah 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 / Not allowed.
4 MAX charge Current 60A Charging with this current for more than 0.5h and the added temperature of battery pack less than 20℃.
5 MAX discharge Current 100A Discharging with this current for more than 10min and the added temperature of battery pack less than 35℃.



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.


Discharge Temperature


-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.



Safety Test

No fire, no explosion

Charing to 3.7v and do nail penetration test, there is no fire, no explosion, no any other obvious changes.


Nail Penetration Test and Overcharge Test

After testing, no fire and no explosion, that is definitely approved than our lithium batteries deserve you.



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 3.90±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 2.30±0.05V
Over-discharge release for each cell 2.80±0.05V
Over-discharge release method Above the release value
Over current Discharge over current protection 400±50A
Protection delay time 50~200ms
Over current release method Release after 8s.
