CATL 314Ah: The New King of Energy Storage The CATL 314Ah 3.2V prismatic cell represents the cutting edge of Lithium Iron Phosphate (LiFePO4) technology. By optimizing the internal structure and active materials, CATL has achieved a capacity of 314Ah and an energy rating of over 1000Wh per cell, all while maintaining the standard dimensions of previous 280Ah cells. This makes it a seamless upgrade for increasing system capacity without changing enclosure designs.
Higher Energy Density: Provides approximately 12% more energy compared to the 280Ah model, allowing you to store more power in the same battery box or container.
Extended Cycle Life: Engineered for extreme durability, the 314Ah cell is rated for 7,000 to 8,000+ cycles (depending on operating conditions), significantly lowering the Levelized Cost of Storage (LCOS).
Extreme Efficiency: With an ultra-low internal resistance of only 0.17 ± 0.05 mΩ, energy loss during rapid charging and discharging is minimized, ensuring peak performance for grid-frequency regulation.
✅ Grade A Guarantee: We supply strictly Grade A cells directly from fresh production lines with original factory QR codes. We do not deal in Grade B or capacity-degraded cells.
🎯 Data Transparency: DLCPO provides full datasheets and professional test reports verifying the 314Ah capacity and low internal resistance for every batch.

No. The dimensions (approx. 72x174x207mm) are effectively the same as the standard 280Ah cell. It is a perfect drop-in replacement for most 280Ah fixtures and racks.
No. The CATL 314Ah uses LiFePO4 chemistry, which is Cobalt-free and Nickel-free. This makes it inherently safer and more environmentally friendly than traditional NCM batteries.
No. Although they look identical, their internal resistance and discharge curves are different. Mixing them will lead to severe system imbalance and reduced performance.
The CATL 314Ah is the latest generation of high-capacity LiFePO4 cells. It packs 1004Wh of energy into the standard 280Ah form factor, offering 12% more capacity without changing dimensions. It is the new gold standard for large-scale BESS (Battery Energy Storage Systems).

Stop charging cells if charging isn’t completed within the specified time.
Stop using cells if the battery becomes abnormally hot, develops an odor, becomes discolored, deformed, or develops any other abnormal conditions during use, charge, discharge, or storage.
Keep away from fire or hot heat sources immediately when a leakage or foul odors are detected. If liquid leaks onto your skin or cloths, wash it out with plenty of fresh water immediately if liquid leaks from cells and gets into your eyes, don’t rub your eyes. Wash your eyes out with plenty of clean water and seek medical attention immediately.
Notice: While 314Ah cells fit 280Ah fixtures, please ensure your BMS is programmed for the higher capacity. Proper compression (300kgf) is critical for reaching 7000+ cycles.
