WeRV Power powered by Prime Battery Solutions

Can I replace my RV battery with lithium?

Sometimes. It is not a safe drop in swap for every RV, and we will not promise that it is.

WeRV Power answer

Check the converter, alternator, solar, BMS, temperature and wiring before you switch an RV to lithium.

What to check

Treat the result as a planning range. The exact fit and the install still get checked against the vehicle, the equipment and the battery maker.

  • Check the converter's charge setting
  • Review the alternator current control
  • Confirm the solar controller settings
  • Check the BMS surge rating
  • Confirm protection from charging in the cold
