| Battery Pack Dimension(L*W*h) and connector type |
432*266*254mm/17*10.5*10inch's(metal case size) | Red and black terminals with M8 screw hole, Terminal height:18mm above case |
| Battery Pack Weight | 40.5±0.5KG | 89±1LBS |
| Rated Capacity | ≥200Ah @ C/3,23ºC/73ºF | Measured as 2.5V cut off at cell level |
| Operating Voltage | 25.6 V (average) @ C/3, 23°C/73°F | Working voltage range is 29.2 ~ 20.8 V |
| Charging Voltage | ≤ 29.2 V @ CC/CV charge mode | Can be changed to 28.8V for longer cycle life |
| Discharge cut off Voltage | 20 ~ 20.8 V (When any cell volt reaches 2.5V may trigger this protection) |
Set device (like a controller) low volt protection much higher to avoid trigger this protection. |
| Maximum Discharge Current | ≤ 200 A @ 30min,23°C,30%≤ SOC ≤100% ≤ 400 A @ 15s, 23°C, 30%≤ SOC ≤100% ≤ 650 A @ 0.5s, 23°C, 30%≤ SOC ≤100% |
Please consider heat accumulation if long time discharging with a large continuous current. |
| Maximum Charge Current | ≤ 100 A @ 60min, 23°C, 20%≤ SOC ≤70% ≤ 200 A @ 5min, 23°C, 20%≤ SOC ≤70% |
Please consider heat accumulation if long time charging with a large continuous current. |
| Battery Cycle Life | ≥ 4000 times @ 80% DOD, ± C/3, 23°C | After cycles can deliver ≥ 75% rated capacity |
| Internal Resistance | ≤ 10 ± 2 mΩ | DCIR test method, @10s, 50% SOC |
| Temperature protection For charging process |
0 ~ 5 ºC ≤ sensor for cell ≤ 52 ~ 58 ºC | If internal sensor detects a temperature that is outside of range, BMS will shut the pack off. |
| Temperature protection For discharging process |
sensor for cell ≤ 65 ~ 70 ºC | If internal sensor detects a temperature that is outside of range, BMS will shut the pack off. |
| Surrounded working condition temperature |
Charge: 5 ~ 45°C Discharge: -20 ~ 55°C |
Suggested for charging: 10 ~ 40°C Suggested for discharging: -10 ~ 45°C |
| Storage Temperature | -10°C ~ 40°C ( for ≤ 3 months) | Keep SOC at 40~60% for long term storage |
The battery pack has handle(s) for lifting and carrying, and an intelligent indicator to show the voltage, current,

All the cells we used in our battery pack are grade A electric vehicle level cells, which fully ensures the performance and safety of the battery pack.
For both warranty and after-sale service, the following will be enforced:
Warranty year(s) for this model of battery pack are specified by supplier. During the warranty period, we will take
responsibility for the replacement or repair for any of the following issues:
• The whole battery pack cannot be charged or discharged.
• Under the standard testing condition, the capacity is less than 80% in the end of the first year, or 70% in the
end of last warranty year (if the last warranty year is provided in the warranty period).
• There is liquid leakage.
• There is some damage on battery pack's case and accessories that are caused by the battery.
• The charger is not working properly.
However, we will not take responsibility in the following situations:
• Expired warranty period.
• Battery damage as a result of improper handling.
• The battery pack is dismantled and converted.
• There is visible damage to the BMS that was not caused by battery failure.
• Damage caused by using an incorrect charger for the pack.
