Upgrade Your RV with Lithium Batteries: Battle Born & Epoch Lithium Power

Upgrading your RV to lithium batteries is one of the best decisions you can make for longer-lasting power, better efficiency, and a more enjoyable off-grid experience. At Fretz RV Service Department, we offer customizable lithium battery upgrades using industry-leading Battle Born and Epoch lithium batteries, designed to enhance your RV’s energy system and eliminate the hassle of traditional lead-acid batteries.

Why Upgrade to Lithium Batteries for Your RV?

Switching to lithium batteries offers numerous benefits over conventional lead-acid options:

  • Longer Lifespan – Lithium batteries last 10+ years, significantly outlasting lead-acid batteries.

  • Faster Charging – Charge up to five times faster, so you spend less time plugged in.

  • Lightweight & Compact – Reduce weight and free up storage space in your RV.

  • More Usable Power – Lithium batteries provide nearly 100% usable capacity, compared to only 50% with lead-acid.

  • Maintenance-Free – No need to check water levels or worry about sulfation.

  • Better for Boondocking – Perfect for off-grid camping, as lithium batteries pair well with solar power.
