INNPO Prismatic LiFePO4 Cell 3.2V 314Ah Grade A

INNPO Prismatic LiFePO4 Cell 3.2V 314Ah Grade A

The INNPO 3.2V 314Ah LiFePO4 prismatic cell has been developed for building high-capacity lithium battery packs used in residential energy storage systems, solar self-consumption, DIY battery projects, industrial applications, campers, motorhomes, marine installations and UPS systems.

With a nominal capacity of 314Ah and a nominal voltage of 3.2V, this cell allows the construction of high-capacity LiFePO4 battery packs while delivering excellent energy density, outstanding thermal stability and an exceptionally long service life.

Manufactured using LiFePO4 (Lithium Iron Phosphate) technology, it provides a safe, reliable and highly efficient solution for applications requiring thousands of charge and discharge cycles with minimal maintenance.

More capacity in the same space

The new 314Ah LiFePO4 prismatic cells represent the natural evolution of the well-known 280Ah prismatic cells. Thanks to improved energy density, they provide higher storage capacity while maintaining virtually the same physical dimensions, allowing larger battery packs to be built without significantly increasing the overall system size.

This improvement increases battery autonomy while reducing the number of daily charge and discharge cycles, improving the overall efficiency of the energy storage system.

The same dimensions as a 280Ah cell with higher capacity

The INNPO 314Ah LiFePO4 prismatic cell maintains virtually the same external dimensions as the widely used 280Ah prismatic cells, making it ideal for both upgrading existing battery packs and building new high-capacity systems.

With dimensions of 174 × 72 × 207 mm, this cell is compatible with many existing LiFePO4 battery designs, allowing users to upgrade from 280Ah to 314Ah cells without significantly modifying the battery enclosure.

• Higher energy capacity
• Same prismatic format
• Ideal for upgrading existing battery packs
• Perfect for new DIY battery projects
