Step up your energy storage game with Grade A Cornex 314Ah Lithium Iron Phosphate (LiFePO4) cells. 

Built for endurance and consistency, these cells are perfect for assembling robust, high-capacity 12V, 24V and 48V battery packs - ideal for solar, campervans, marine systems, and off-grid setups.

Unmatched Durability and Lifespan

  • Designed for longevity with up to 8,000 cycles at 70% SOH (6,000 at 80%), providing years of dependable energy storage.
  • Advanced LiFePO₄ chemistry and rugged construction ensure stable performance under demanding off-grid conditions.

Exceptional Capacity for Extended Use

  • With a 314Ah capacity, these cells deliver serious storage for high-demand applications.
  • Reliable operation across a wide temperature range (discharge from -20°C to 60°C) makes them suitable for remote and variable environments.
  • High round-trip efficiency (≥94%) maximises usable energy and reduces losses during charge/discharge.

Seamless Integration

  • Screw terminals allow straightforward assembly into custom battery packs.
  • Supplied ready for integration with bus bars and appropriate fixings (BMS required for safe operation).

Important: These are raw cells, not finished batteries. Only purchase if you’re confident working with lithium cells - they can be hazardous if mishandled or shorted.
