2.56kWh 12.8V 200Ah LiFePO4 Battery with High Current Power Output
This 12.8V, 200Ah LiFePO4 battery combines 2.56kWh of nominal energy with a 200A current platform. It can be evaluated for compatible electric-mobility, emergency-power, UPS and high-demand DC applications.
The battery is a standalone module rather than a complete vehicle or backup system. The controller, charger, inverter and electrical protection must be selected separately.
Rated charging and discharging current is 200A, with 205A listed for one second. The rated battery-side power is 2.56kW.
Cables, terminals and protection devices should be selected according to the actual operating current. Motor controllers and inverter loads should also be checked for startup demand.
The 200Ah capacity supports longer operation than smaller 12V batteries under comparable load conditions. For electric-mobility projects, total battery-bank voltage and controller compatibility must be confirmed.
The source lists support for series and parallel arrangements, but the final battery-bank design should be approved together with the charger and connected equipment.
| Nominal Rating | 12.8V / 200Ah / 2.56kWh |
| Cell and BMS Configuration | 4S2P / 4S200A BMS |
| Operating Voltage Range | 10.0–14.6V |
| Current Capability | 200A Rated / 205A for 1 Second |
| Power Capability | 2.56kW Rated / 2.62kW for 1 Second |
| Cycle Reference | At Least 6000 Cycles at 80% DOD and 25°C |
| Expansion and Terminal | Four Series / Four Parallel Listed / M8 Terminal |
| Dimensions and Weight | 502 × 186 × 243mm / 19.62kg |
| Protection and Temperature | IP67 / Charge 0°C to 50°C / Discharge -10°C to 60°C |
It can be evaluated when the controller voltage, motor demand, charger and battery-bank design are compatible.
It is the listed rated current, but actual operation also depends on temperature, battery state and system design.
Series use is listed, but the permitted configuration and compatible charging equipment should be confirmed first.
Remote data is listed as unavailable. Optional display or Bluetooth configurations should be confirmed separately.
Provide the controller voltage, motor power, operating current, charger specification and daily duty cycle.
Send the controller, charger and load specifications to review battery-current and voltage compatibility.
