Product Description
EVE LF280K 280Ah 3.2V LiFePO4 Prismatic Rechargeable Cell
EVE LF280K V3 is a Grade A 3.2V 280Ah LiFePO4 prismatic rechargeable battery cell manufactured by EVE Energy, a global top-3 lithium battery supplier. Adopting advanced lithium iron phosphate chemistry and automated production lines, this cell delivers ultra-high capacity, long cycle life, low internal resistance, and exceptional safety, making it the ideal core component for residential/commercial energy storage systems (ESS), solar power systems, UPS backup, electric vehicles (EV), RV, marine power, golf carts, and DIY battery packs. With up to 8000 cycles @ 0.5C/0.5C (25℃, 80% SOH) and stable discharge performance, it ensures reliable, long-term power supply for both industrial and consumer applications.
Key Features & Advantages
- Ultra-High Capacity & Energy Density: Nominal capacity: 280Ah (actual tested capacity up to 310Ah+), high energy density for compact, high-power battery systems.
- Extra-Long Cycle Life: Up to 8000 cycles at 0.5C charge/discharge (25℃), 70% capacity retention; 6000+ cycles at 1C/1C, far exceeding standard lithium-ion cells.
- Low Internal Resistance & High Efficiency: Internal resistance ≤0.23mΩ, low heat generation, high discharge rate (1C continuous, 2C pulse 30s), stable voltage platform, and high energy conversion efficiency.
- Superior Safety & Thermal Stability: LiFePO4 chemistry with built-in explosion-proof valve, aluminum prismatic casing, and multi-layer safety design: no fire, no explosion, wide operating temperature (-20℃ ~ 60℃).
- Grade A Quality & Perfect Consistency: 100% brand new Grade A cells, original factory QR code, strict capacity/voltage/IR matching, low self-discharge (≤3% per month), stable batch performance.
- Wide Compatibility & Easy Assembly: Standard M6 threaded terminals, ready for series/parallel connection; compatible with BMS systems for ESS, EV, RV, solar, and industrial backup.
