Lithium-Ion Batteries: LiFePO4 batteries are becoming increasingly popular in the RV community due to their high energy density, lightweight, long lifespan, and fast charging capabilities. They offer deeper discharges, greater usable capacity, and a longer lifespan compared to lead-acid batteries.
Focus on batteries with a higher amp-hour (Ah) rating. For most RV adventures, a capacity ranging between 100-200 Ah should suffice. Less than 100 Ah and you’re looking at a lifestyle of charging gadgets and not much else. More than 200 Ah, and not even the icy tundras of Canada will be able to stop your off-grid expeditions!
You can also get flooded lead acid batteries which are sealed and sold as being maintenance free. The usable capacity of a battery indicates how much of the battery can be used before it must be recharged. The usable capacity of a flooded lead acid battery is around 30-50% of the total capacity.
Power consumption from personal electronics, TVs, laptops, lights, etc. can be estimated. A battery bank with 400Ah to 600Ah of usable capacity is a good starting point. Check out this article for several examples of standard off-grid RV system configurations. What is the usable capacity of a Battery Bank?
Let’s explore the three main types of readily available RV batteries. Flooded Lead-Acid (FLA) Batteries: These are the most common and traditional type of RV battery. They contain a liquid electrolyte (dilute sulfuric acid) that submerges the lead plates.
In addition, Flooded batteries are also the most demanding in terms of maintenance as their electrolyte needs to be regularly topped off. On average, Flooded or Wet-Cell Lead-Acid batteries can last for around 500 life cycles. Depending on how you use your RV, this translates to approximately 2-4 years of reliable use.
