"Standard Charge" means at 25±2℃ charge to limit voltage with 0.33C constant current, then charge with constant voltage until current less than 0.02ItA.
3.3 Quick Charge Mode
" Quick Charge" means at 25±2℃ charge to limit voltage with 0.5 C constant current, then charge with constant voltage until current less than 0.02ItA.
3.4 Standard Discharge Mode
"Standard Discharge" means at 25±2℃ discharge to the cut-off voltage with 0.33C current.
3.5 Quick Discharge Mode
"Quick Discharge" means discharge to the cut-off voltage with 0.5C current.
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. |
| 7 | Discharge Temperature Characteristics | -20℃ | 70% | At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage. |
| 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. |
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.

| 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℃ |

How to choose a suitable battery pack?
- battery voltage is the same with the original.
- battery size same with the original. Or similar/smaller.
- battery plugs same with the original (check the plug diagram)
Match the above three conditions, in general, this battery can be used.
The larger of MAH, the longer use time. Different voltage, battery size, shape, can be same voltage, because the battery combination of different ways, the shape is not the same. You can leave a message about your old battery, please pay attention!!!
Quality Control
Capacity test, High current discharge test,Low temperature test, Short circuit test, Over charging test,
