EVE LiFePO4 280Ah Prismatic Cell (Grade B)

Sold out

These 280AH EVE Prismatic cells are Grade B Lithium Iron Phosphate batteries, often referred to as LiFePO4 Prismatic Cells.

LiFePO4 cells are ideal for off-grid solar batteries, campervan batteries and are generally renowned for being the best DIY battery for energy storage applications. 

EVE categorised Grade B cells prevent them from being used in electric vehicle applications, but they are an excellent fit for energy storage and solar applications.

Grade B cells have the same capacity and internal resistance as Grade A cells, this can make it very difficult to distinguish between the two. In the interests of full transparency, Fogstar offers both Grade A and Grade B cells supplied directly by EVE.

All of the Fogstar supplied Grade B EVE 280ah cells are capacity tested, matched and labelled prior to delivery. Fogstar quality standards stipulate the minimum supplied cell capacity is 277ah. 

These cells require connecting together with the included busbars (Nickel Plated Copper) and screws (8 nuts and bolts). Please ensure you are familiar with these cells before ordering as they can be dangerous if shorted.

We recommend this product is used with a BMS. We also stock a wide range of 12v, 24v and 48v BMS by both JK & JBD. All BMS variants in the Fogstar range have been selected to work perfectly with the 3.2V LiFePO4 Lithium Prismatic Cells we stock.
