ENERpower Battery LiFePO4 12V (12.8V) 50Ah (640Wh) – replaces lead-acid batteries 12V, lead-gel batteries 12V

Important General Information

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.


  • High-quality production – partial production in Germany
  • BMS with an integrated passive balancer
  • BMS with protection against overcharge, deep discharge, over-discharge (temperature monitoring)
  • 50Ah at LiFePo4 is equivalent to approx. 90Ah-100Ah at lead gel batteries
  • directly from the manufacturer
  • Rechargeable – After 1800 complete charging cycles still preserves 80% of its original capacity
  • No memory effect – charge the battery whenever you want
  • Environmentally friendly according to EU Directive 2002/95/EC (RoHS)
  • UL and IEC 62133
