Important General Information

ATTENTION! Delivery expected only in late February / March 2019

Our selection of LiFePo4 batteries is ideal as a lightweight and long-lasting replacement for lead batteries (lead acid).

With a much lighter weight, rugged tension and long lifespan (approx. 2000 charge cycles), this lithium technology brings important advantages over conventional lead battery technology.

When you buy a battery from ENERpower, you buy a product from a specialist with its own production line.
