Best Lithium Batteries for RV

Are you in the market for a new battery and are considering a lithium battery for your RV? Want to enjoy all the comforts of home life and use your appliances in your RV on the go?  Either way, you will want and need a battery you can rely on and will last longer than other batteries. In this article, we highlight what we believe to be is the best lithium batteries for RV use.

What is a Lithium Battery? 

A lithium-ion battery is a rechargeable battery where lithium ions move from a negative electrode to a positive electrode upon discharge and then back during charging. This provides high energy density and low self-discharge (power leakage). Because of the rather low self-discharge rate, lithium-ion batteries take a long time to discharge and provide a long useful life making them a good investment.

Lithium-ion batteries retain their power, provide a more constant charge,  are more reliable than lead (SLA) batteries. In addition, they can be recharged multiple times. 

They were developed by Sony and initially found common use in electronics and now electric vehicles and other commercial applications. 

Lithium Iron Phosphate (LiFePO4) batteries have similar features as lithium-ion batteries and the same advantages over lead (SLA) batteries.

The Difference Between Lithium-ion and Lithium Iron (LiFePO4) Batteries

Since we are discussing Lithium batteries, we should discuss the difference between Lithium-ion batteries and Lithium Iron Phosphate (LiFePO4) batteries, as we have recommendations for both types of batteries. 

The main difference between the two is the chemistry, with both being superior technology over lead (SLA) batteries. LiFePO4 is a newer type of battery and gaining recognition and popularity that is superior to Lithium-ion at a comparable price.

Lithium-ion has a higher energy density than lithium iron phosphate, so it discharges a bit faster than lithium iron phosphate batteries. Lithium iron phosphate has a lifecycle of 1,000-10,000 cycles, whereas lithium-ion, has a life cycle of 500-1,000 cycles. 

Lithium iron phosphate batteries are more stable and perform better at higher temperatures. Something to keep in mind, if you travel through the southwest often. Something to keep in mind, if you travel through the southwest often.

The summary is that while LiFePO4 is superior to Lithium-ion, either battery is an excellent choice to install into your RV and provides the necessary power to have a tremendous experience during your travels.

What is the Best Lithium-Ion Battery for RV Use

With the overwhelming number of brands for purchase (with new products coming all the time),  finding the best lithium battery for your home can be a lot of effort. When considering which one to purchase, the top features are capacity, durability, life cycles (life expectancy), and maintenance – or lack of maintenance. 

You will also need to consider where you will use your RV will be used for and what type of power requirements does it will have, especially if boondocking or dry camping. Lithium batteries are sealed, they require no maintenance during use unlike lead batteries, on the other hand, may require topping up with distilled water on the road. 

Also, lithium-ion and LiFePO4 batteries handle temperature fluctuations very well, allowing them to maintain stable performance in any temperature, hot or cold.    

Finally, our budget is also a consideration and if you only take a few trips every year, or most or all of your RV travels allow for shore power hook up, then a less expensive lead battery could work for you.  

That being said, another way to look at it as an investment is to think about how long will your battery last. On average, lead-acid batteries can last up to 5 years with proper maintenance. If a Lithium-ion or LiFePO4 battery lasts up to 10 times longer, with most rated at 2x-3x longer.  Most have a 10-year service life expectancy. 

We believe either choice of lithium-ion or lithium iron phosphate is worth the extra expense, will provide a good investment over time, and are often the best choice, as they charge faster, weigh less than lead batteries, and have a longer life. 


Our Lithium Battery for RV Recommendations 

Here are our five recommendations to consider for the best lithium battery for RV use:   

1. Ampere Time 12V 200Ah Lithium-ion Deep Cycle Battery

  • Has built-in Battery Management System (BMS) to protect from over-charge, over-current, or short circuit.

Wrapping Up

One of the many reasons why lithium-ion batteries are the best is because they are maintenance-free, rechargeable, offer a longer service life, and much lighter than lead (SLA) batteries.  More importantly, the RV lithium-ion and lithium iron phosphate batteries are very safe and also environmentally friendly constructed from non-toxic renewable materials.

So spend your time outdoors enjoying the road,  seeing new places, meeting new people, and do not worry about whether your battery will leak or the impact of your carbon footprint. We hope that our recommendations serve you well. Thank you for reading. Happy and safe travels
