Our 305Ah Envision AESC Prismatic cells are Grade B Lithium Iron Phosphate (LiFePO4) batteries. These cells are ideal for compiling 12V off-grid batteries for solar, campervans and boats. They are generally renowned for being the very best DIY battery for energy storage.

They have a lifespan of >3500 cycles and charge at 0.5C (0.05C termination current up to 3.65V) with discharge 0.5C (down to 2.5V).

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.

Busbars and screws are included
