Product Description
CATL 314Ah LiFePO₄ Prismatic Battery Cell – 7000+ Cycles, Higher Energy Density
Actual capacity >320Ah | 0.17mΩ internal resistance | Same dimensions as 280Ah | 1004.8Wh per cell
The CATL 314Ah LiFePO₄ battery cell is a high-capacity energy storage cell, serving as a direct upgrade to the popular CATL 280Ah LiFePO₄ cell. It delivers 12% higher capacity (actual >320Ah) while maintaining identical external dimensions, making it a drop-in replacement for higher energy density. Manufactured by Contemporary Amperex Technology Co. Limited (CATL), this cell offers exceptional safety, reliability, and a cycle life of more than 7000 cycles at 70% State of Health (SOH).
This prismatic cell is widely used in residential, commercial, and industrial energy storage systems (ESS), and can be combined to form larger battery packs with higher capacities.

Typical applications include: Residential Solar Storage, Commercial & Industrial ESS, Utility-Scale Battery Banks, Telecom Backup, UPS Systems, Marine Propulsion, and Electric Vehicle (EV) packs.
1. Always use a BMS – monitor voltage, current, and temperature during charge/discharge.
2. Avoid heat & fire – keep away from heat sources, open flames, and corrosive chemicals.
3. No short circuit – never reverse polarity or short-circuit terminals with metal objects.
4. Do not mix cells – use cells of same model, capacity, and batch for pack assembly.
5. No mechanical abuse – do not crush, puncture, drop, or disassemble the cell.
6. Proper storage – store at 30%~50% SOC in cool, dry place away from direct sunlight.
7. Protective gear – wear insulated gloves when handling cells.
8. If damaged – immediately stop use if cell leaks, smokes, or deforms; contact supplier.
