FAQs

1. Are RV and car batteries the same thing?

The battery on the RV's hood is a normal car battery, present in all other car types. This type of battery is also referred to as the starting battery or the chassis battery. It is meant to supply the engine with high bouts of power to start the car for just a few seconds or minutes.

Now, the interior living space of your RV requires power to function normally. For instance, lighting the RV when it is dark, powering appliances such as refrigerators or TVs, and charging devices such as smartphones. Although these types of batteries look similar to the chassis battery, they are designed to provide power for longer hours continuously. Also, they experience deep discharges before recharging.

2. How long can a 100Ah battery sustain me in an RV?

A 12V 100Ah battery delivers 1200Wh of energy output. If your RV utilizes 100W per hour, a 100Ah battery will last for approximately 12 hours by powering a mini fridge, charging a smartphone, and providing LED lighting.

This applies to LiFePO4 batteries since they can utilize 100% of their capacity. However, lead-acid batteries can only be discharged up to 50%, reducing their runtime to 6 hours.
