3. Electrical Characteristics & Test Condition.
@Ambient Temperature 25±5℃ & Humidity 45%~75%.
| NO | Items | Criterion | Condition | |
| 1 | Internal Impedance | ≤30mΩ | Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument. | |
| 2 | Nominal Capacity | ≥98Ah | 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 | 80A | 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 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. | |

| 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±100A |
| Protection delay time | 50~200ms | |
| Over current release method | Release after cutoff the load. | |
Battery temperature | Battery Over temperature | Protection @65±5℃, Release @55±5℃ |
