2 Myths About RV Lithium Batteries


2 Myths About RV Lithium Batteries

A successful RV trip requires a successful RV battery. Traditionally, most RVers have stuck to flooded or lead-acid batteries due to their affordability and accessibility. However, lithium RV batteries are growing in popularity. As new models grow safer and more efficient, many RVers have decided that lithium is the right choice for their vehicle. Is the same true for your RV? The only way to find out is to learn more about lithium RV batteries. There is a lot of false information and many misconceptions about these batteries. Make sure you have your facts straight by learning the truth behind these myths about RV lithium batteries.


Myth: Lithium Batteries Are Fragile or Dangerous

Many people hear the term “lithium-ion battery” and picture a dangerous device that might catch fire or explode. This is a common misconception that stems from manufacturing errors with cellphones or laptop batteries. The truth is that RV lithium batteries use a newer lithium-ion phosphate design known as LiFePO4. This non-combustible solution prevents your RV battery from overheating, making it both safe and durable—even in colder climates.

However, it’s important to install battery warmers to help insulate your lithium RV battery and prevent it from taking damage in freezing temperatures. These warmers—along with RV tank heating pads and other products from UltraHeat—make it easy to protect your RV in all kinds of weather.


In addition to the lithium-ion phosphate design, RV lithium batteries contain a built-in battery management system that manages the charge rate, performance, and other elements. This helps create a safer battery with the longest possible lifespan.


Myth: Lithium Batteries Aren’t Worth the Cost

Cost is a major factor when deciding which type of RV battery is right for you. Of course, affordability is based on your budget and how much you want to spend. However, one of the most common myths about RV lithium batteries is that they’re far too expensive. Are they really worth that much money? While it’s true that lithium batteries are more expensive, you must also consider the fact that they will last longer. A traditional RV battery can last a couple of years and requires a fair amount of maintenance during that time. Lithium RV batteries, on the other hand, require little to no maintenance and can last for ten years or more, thereby reducing their cost in the long run.
