280Ah LiFePo4 Battery Cell with 8000 Cycles and 1C Max Discharge for Energy Storage
Manufactured with Ganfeng LiEnergy cells and customized by Shenzhen Jianheng Technology Co Ltd (Jianheng), the OID71173204F280AH is a 3.2V prismatic LiFePo4 battery cell offering 280Ah nominal capacity. Designed for demanding energy storage applications, solar systems, and electric vehicles. With ultra-low internal resistance (≤0.25mΩ), excellent cycle life (8000 cycles to 70% SOH), and wide temperature operation range (-30°C to 60°C discharge, 0°C to 60°C charge), this cell delivers reliable power and long-term value.

- Aluminum case with positive polarity – avoid short circuits
- Terminal material: AL1060, plastic PPS upper insulator
- Welding area limited to Φ4mm~Φ14mm around positioning hole, depth <2.5mm (PPS melting prohibited)
- Built for BMS integration: Overcharge, over-discharge, over-current, short circuit, and thermal protection required
- Storage recommendation: Keep SOC 25%~40% and recharge every 3 months
- Do not charge below 0°C; below 10°C, constant voltage charging is prohibited (cut-off ≤3.55V)
- Comply with all safety precautions – improper handling may cause fire or explosion
The OID71173204F280AH must be used with a Battery Management System (BMS) monitoring voltage, current, and temperature. End of life when internal resistance exceeds 150% of initial value or capacity drops below 70%. The aluminum shell is positively charged – avoid any overlapping or short circuit.
