OID 3.2V 314Ah LiFePO4 Battery Cell with 8000 Cycles and 1C Discharge for Solar & EV Applications

Introducing the OID71174207F314AH, a premium rechargeable lithium iron phosphate (LiFePO4) prismatic battery cell manufactured by Shenzhen Jianheng Technology Co., Ltd. Designed for demanding energy storage applications, this 314Ah cell delivers exceptional cycle life, thermal stability, and reliable power output. Whether you are building a solar energy storage system, an electric vehicle (EV) battery pack, or an industrial backup solution, this cell meets the highest standards of safety and performance.

• High Capacity: 314Ah nominal capacity, 984Wh energy at 45°C.
• Ultra-Long Cycle Life: 8000 cycles at 70% capacity retention (0.5C, 25°C).
• High Discharge Current: Supports 1C continuous discharge current (314A).
• Wide Temperature Range: Charge: 0°C to 60°C; Discharge: -30°C to 60°C.
• Low Internal Resistance: ≤0.25mΩ (1KHz AC) for high efficiency.
• Excellent Safety: Stable LiFePO4 chemistry with explosion-proof valve.
• Preload Recommendation: 500N – 5000N initial preload for optimal lifespan.

• Self-discharge Rate: ≤3.5% per month (25°C, 40% SOC after 3 months).
• Capacity at Low Temperature (5°C): ≥804Wh (0.5P, 2.5V-3.65V).
• Regeneration Pulse Charging (10s): Up to 1.5C (at 20°C-40°C, 30%-100% SOC).
• Regeneration Pulse Discharging (10s): Up to 2.5C (at 20°C-45°C, 20%-90% SOC).
• Swelling Force at 80% SOH: ~30000N (under 15mm steel plate test).
• Recommended Assembly Gap: 0.5 – 1.5mm between cells to accommodate swelling.

This LiFePO4 cell must be used with a qualified Battery Management System (BMS) that provides over-voltage, under-voltage, over-current, short-circuit, and temperature protection. The aluminum shell is positively charged; avoid any short circuit. Storage below 5% SOC for more than 7 days is not permitted. For storage longer than 30 days, maintain SOC between 25%-40% and perform a full charge/discharge cycle every 3 months. Always follow the specified preload (300±50Kgf during measurement) and ensure proper heat dissipation, waterproofing, and dustproofing in final battery packs.
