Motorhome house and starting batteries

Most motorhomes ask their batteries to do two jobs. One starts the engine every time. The other runs the living area on deep cycle power.

Motorhome power

Learn the difference between the starting battery and the house bank, and plan safe charging from the alternator, generator, shore power and solar.

Keep the two jobs clear

The chassis battery starts the engine. The house bank runs the living area. Before you combine or replace them, check the isolation and the charging controls.

  • Find the chassis battery and the house bank
  • Test how the isolator or DC to DC charger behaves
  • Check generator and converter charging

Avoid a charger mismatch

A switch to a different battery type can affect the converter, the alternator, the solar controller and the battery monitor.

  • Write down every charging source
  • Confirm the voltage settings on each one
  • Check the lithium battery's cold weather protection

Advanced options

Plan around how you use the battery

Use this when you know your system voltage, daily energy use, cart setup or accessory load.

For modest RV use, start with 800 to 1,500Wh a day. Then adjust it from your real loads.
