Our 280Ah Envision AESC Prismatic cells are Grade B Lithium Iron Phosphate (LiFePO4) batteries. These cells are ideal for building off-grid solar systems, campervan power supplies, and boat electrical systems.
While classified as "Grade B," these undergo testing, as well as being matched and balanced, to ensure consistent performance and reliable capacity.
Key Features:
- Grade B LiFePO4 chemistry: Offers a balance between affordability and performance.
- Exceptional lifespan: Delivers at least 6,000 cycles when used at a depth of discharge (DOD) of 80%.
- Safe and efficient: Operates within a 0.5C charge and discharge rate, with a voltage range of 2.5V to 3.65V.
- Easy connection: Includes nickel-plated copper busbars and screws for assembly.
Important safety note: Lithium iron phosphate batteries can be dangerous if mishandled. Ensure you have a good understanding of safe battery handling practices before working with these cells.
