| NO. | Items | Criteria | Testing method |
| 4.1 | Rated Capacity | 200Ah | 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 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity. |
| 4.2 | Minimum Capacity | 190Ah |
| 4.3 | Internal resistance | ≤25mΩ | 50% battery SOC state frequency of 1 KHZ ac resistance tester |
| 4.5 | Cycle life (DOD100%) | ≥1600cycle | Discharge with the current of 0.33C 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. |
| 4.6 | 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% |
| 4.7 | Charge Retention ability | Residual capacity≥80% | Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage. |
| Recovery capacity≥90% |
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.

Applications:
Golf trolly , Wireless camera, surveillance cameras, wireless infrared detector, car LCD TV, portable DVD, personal treatment system, PDA personal data assistant, personal communications systems, walkie-talkies, digital cameras, camcorders, video cameras, Bluetooth devices, CD players, MD players, MP3 players, smart cards, aviation model LED lights and other fields can be used
Features:
The battery uses original brand ion batteries, with a small internal resistance, big capacity, cycle times and more, no memory effect, etc; internal circuit for multiple protection design, can prevent over charge, over discharge, over current; production process quality inspection and monitoring the use of computers to ensure superior battery performance.
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!!!
