RV battery as outdoor power source

Every RV has either a battery or a series of batteries installed for providing a source of power in the absence of an external power source. Most RV's will come factory with a Deep Cycle Battery. Deep cycle batteries can run the electronic equipment that uses low power, things like the lights, and even some small appliances.

Where it becomes important is when you are dry camping (no shore power) and the reserve power (amp-hours) in your RV batteries is all you have to supply your electrical needs. A typical deep-cycle RV battery will be rated around 80 amp-hours, which in theory would supply one amp for 80 hours.

If you want to be able to power both a small RV and your toys, a 48-Volt LiFePO4 Lithium-ion deep cycle battery is a good choice. These batteries can power an off-road electric vehicle.

The DC electrical system uses a 12-volt battery that powers most of the basics in the RV, things like lights, the water heater, water pump, carbon monoxide detector, and the refrigerator.

Whether running an Air Conditioning, cooking or taking showers, it will require power (and water). Some RV's have basic power sources like the battery and propane tanks, while some others are equipped with generators, power inverters and solar panels for uninterrupted electricity. So, how do campers get power?

When you connect your RV to an on-grid dedicated AC power supply, you are connecting to a power supply of either 30 or 50 amps. Once connected, running all your appliances, including Air Conditioning, heaters and Microwaves will run without issue.
