Product Description
EVE LF280K 280Ah 3.2V LiFePO4 Prismatic Rechargeable Cell
The 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. Utilizing advanced lithium iron phosphate chemistry and automated production lines, this cell delivers ultra-high capacity, long cycle life, low internal resistance, and exceptional safety performance. It serves as the ideal core component for residential and 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 at 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+), providing 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, significantly 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
