2023 brings with it the continued domination of lithium batteries over the RV market. This comes as no surprise since RV owners will always face the challenge of optimizing what little space they have.
Naturally, lithium batteries, particularly LiFePO4 variants, are a big help in this regard. They are lighter, more compact, and more powerful than their lead-acid counterparts.
It stands to reason why anyone with an RV would want to invest in such a battery.
So to make things easier, we’ve listed 10 of the best lithium batteries for RVs in 2023.

How to choose the correct lithium RV battery
Before you go about purchasing a lithium battery for your RV, it’s vital that you consider your energy requirements. Skip this step, and you risk purchasing a battery that is either too small or too large for your setup.
With that out of the way, let’s look at the characteristics that make up a quality lithium RV battery.
Compact
Quality lithium RV batteries need to be as compact as possible relative to their capacity. This is particularly important in RVs because you’re working with limited space. Moreover, compact batteries are more convenient to transport, handle, and install.
Another reason is that compact batteries typically have a higher energy density, meaning they can store more energy in a smaller space. High energy density is essential in applications that require a high power output or extended run time.
High-capacity
High-capacity lithium batteries are practical in pretty much any energy storage scenario you can dream up. But they are particularly handy for RV owners.
A high-capacity battery will allow you to store more energy, which translates to a longer run time for your RV electrical appliances. This is particularly useful if you’re dry camping or boondocking.
Moreover, high-capacity batteries tend to have longer lifespans, can output more cycles and require less recharging, making them more cost-effective and less inconvenient in the long run.
Depending on your energy needs, 100Ah to 300Ah make for good RV lithium batteries.
Lightweight
All RVs come with a gross vehicle weight rating (GVWR). This rating, determined by manufacturers, indicates the heaviest weight at which an RV can operate safely.
It stands to reason why quality lithium RV batteries must be as light as possible relative to their capacity.
For starters, a lighter battery means you’ll have more weight available for other necessary items. Moreover, it’ll be easier for you to handle in the confines of your RV.
Then there’s the issue of fuel consumption. Every item you place in your RV adds to it’s overall weight. The heavier your RV, the more fuel it’ll burn through. Nevermind the wear and tear on its engine and suspension.
If possible, try to avoid going over 70 lbs.

Powerful
Higher-end RV setups don’t just include lights and general electronic devices; they also tend to have units, microwaves, and even pool tools.
If you want to include any of the above in your RV, it’s essential that you look for lithium batteries with high power output.
Doing so will allow you to power these heavier loads while also having the ability to recharge your battery quickly.
Depending on your energy needs, anything above 1.2 kWh will generally suffice.
Durable and maintenance-free
The last thing you need while travelling with your RV is more maintenance, especially on battery storage.
Most durable lithium RV batteries will provide 2,000-5,000 charge and discharge cycles. While higher-end offerings can output 8,000 cycles or more.
But there’s more to a battery’s durability than its cycle life. A durable lithium battery should also come with ingress protection and a quality battery management system (BMS) to protect it from external and internal issues.
