Reliable 314Ah Cells for 16kWh-Class Energy Storage
The CATL 314Ah LiFePO4 cell is designed for energy storage applications, combining 314Ah capacity, 3.2V nominal voltage and 1004.8Wh nominal energy per cell.
With 16 cells in series, you can build a 51.2V 314Ah battery with approximately 16.08kWh of nominal energy — a practical capacity for home solar storage, off-grid systems and larger DIY LiFePO4 battery projects.
Key Features
1. Certified Grade A Quality: 100% brand new, genuine prismatic LiFePO4 cells. No recycled, no refurbished, and no salvaged components.
2. Capacity Freedom: Choose between the industry-standard 280Ah or the high-density 314Ah to perfectly match your power requirements.
3. Industry-Leading Cycle Life: Achieve 7000+ deep charge/discharge cycles at 80% DOD. Build it once and rely on it for years.
4. Superior Efficiency: Ultra-low internal resistance ensures consistent power output, faster charging, and less thermal buildup.
5. Perfectly Matched: Every order is batch-matched for capacity (Ah) and internal resistance (mΩ) to ensure your pack stays balanced right out of the box.
6. DIY & Professional Ready: Standard terminal dimensions make these compatible with all common 4S, 8S, and 16S BMS configurations.
