RV Battery Upgrade

Battery system upgrades — lead-acid to lithium conversions, AGM installations, battery bank sizing, and charging system compatibility updates.

Service Details

More Power, Longer Runtime

The battery bank is the foundation of your RV's electrical system. Upgrading from old flooded lead-acid batteries to AGM or lithium can dramatically increase your usable capacity, reduce weight, and extend battery life.

Diego sizes your battery bank based on actual usage, installs the batteries, and updates your charging system (converter, solar controller, alternator charger) to match the new battery chemistry.

  • Lead-acid to lithium conversion
  • AGM battery installation
  • Battery bank sizing and configuration
  • Converter charging profile update
  • Solar charge controller compatibility
  • Battery monitor installation
