5 Best Lithium-Ion Batteries for RV Solar Power Worth Considering

Table of Contents

If you own an RV, then you’ll need an external power source to keep things powered when the engine isn’t running.

Solar panels are a great option for this, but you also need an adequate battery to store any excess solar power.

A lithium battery is usually the best battery for this job.

We’ve compiled a list of some of the best lithium-ion batteries for RV solar power you can get online.

Keep reading if you’re interested in finding out more.


Why You Should Consider a Lithium-Ion Battery for Your RV

Lithium-ion batteries offer considerably more advantages over battery types like AGM batteries. Let’s go over some of the key differences.

Lithium batteries have a considerably longer lifespan than AGM batteries and will last up to three times as long in most situations.

Lithium batteries are also able to charge and discharge incredibly efficiently, up to almost 100% in both cases.

They also don’t suffer from voltage sag, meaning a lithium battery at 20% charge will produce the same volts as a lithium battery at 100% charge.

Lithium batteries are also much smaller than other types of batteries, which makes them far easier to store and use aboard an RV.

So, there’s no reason to not use a lithium battery in your RV!

This lithium-iron battery from Renogy should probably be one of your first choices if you’re serious about RV solar power storage.

What sets this battery apart from other batteries is that it’s a “smart” battery.

This means it comes with a battery management system that can help protect the battery from becoming damaged if it’s exposed to abnormal storage conditions.

Not only that, but it helps to manage the battery’s charging and discharging processes, and it’s even available with a small monitoring screen that you can connect to the battery through a built-in RJ45 communication port.

The monitoring screen lets you view your charge and discharge readings in real-time.

At just under 12 kilos, Renogy’s battery is also fairly lightweight as far as these types of batteries go.

It also comes with integrated handles to help make moving it around easier.

This battery is also designed to be durable and long-lasting and will probably last you for at least 3,000 cycles.

However, all of these features come at a price, namely the actual price itself.

Features like the smart monitoring system cause the cost to climb.

Pros
  • Low self-discharge rate
  • Resistant to cell corrosion
  • Able to resist high and low storage temperatures
  • Waterproof
  • Excellent for RV solar power storage
  • Comes with a built-in monitoring system
Cons
  • Very expensive

2. SHUNBIN 12V Lithium-Ion Battery

Like the Renogy battery we just mentioned, this battery from SHUNBIN also contains a built-in battery management system protection board, which frankly you should expect from any decent battery.

It also comes with an integrated digital voltage display.

The downside of the SHUNBIN battery over the Renogy battery is that the SHUNBIN battery is much larger and bulkier.

It still comes with attached handles for moving it around, but the SHUNBIN battery weighs about twice as much as the Renogy battery.

Also, the SHUNBIN battery can’t handle high temperatures nearly as well as the Renogy battery can.

However, the SHUNBIN battery is considerably less expensive than the Renogy battery by over $200, which is a considerable difference.

It also comes with a 3-year warranty, and it’s a pretty decent pick overall if you want a capable battery that you don’t plan on moving around often.

Pros
  • Charges quickly
  • Available with a 3-year warranty
  • Comes with a battery management system
Cons
  • Overly bulky design
  • Considerably heavier than other similar batteries

3. Go Battery Military Deep Cycle Battery

If you want a tough, long-lasting battery, this offering from Go Battery may be exactly what you’re looking for. 

Like any decent battery, the Go Battery contains a built-in battery management system that protects your battery from common causes of failure like over-discharge and short-circuiting caused by overcharging.

It comes with a small digital volt display, and it also comes with an integrated 12-volt outlet which is a feature that most of these batteries don’t have.

And at a little under 14 kilos, this battery isn’t too hefty either.

The great thing about lithium-ion batteries is that on average they are 50% lighter than a lead-acid battery of the same capacity, yet lithium-iron batteries will last eight to ten times longer than a comparable lead-acid battery.

If stored right, the Go Battery will be able to last you for up to 10 or even 20 years!

During this time, it will be capable of between 4,000 to 10,000 charging cycles, which is by far the greatest longevity of any battery on this list.

And on top of all of this, the Scream Power is considerably less expensive than either the Renogy battery or the SHUNBIN battery.

Pros
  • Comes with a 12-volt outlet and USB outlet for quick charging of small appliances
  • Extremely long-lasting, capable of many thousands of charging cycles
  • Comes in a durable steel case
Cons
  • The most expensive battery on this list

4. Orient Lithium-Iron LiFePO4 Battery

Last update on 2024-01-30 / Affiliate links / Images from Amazon Product Advertising API

If you’re looking for the most compact battery design available, you could do a lot worse than this lithium-iron battery from Orient.

Weighing in at only 8 kilos and coming in a slim shape, this is a battery that’s super easy to use either on its own or with multiple batteries together in a sequence.

Despite its small size, it’s still about as powerful as you’d expect from an RV battery.

Unlike the other batteries we’ve mentioned so far, however, Orient’s battery doesn’t have any kind of protection from a battery management system or even any kind of display showing you the charge or voltage levels.

It’s about as basic as a battery gets, but that’s kind of the point.

Despite its simplicity, this is a pretty durable battery, capable of lasting you over 8,000 charging cycles.

Also, each battery cell is tested individually by the manufacturer before the batteries are shipped out, to ensure that everything is working correctly.

Overall, this is the best battery for you if you’re after compactness and simplicity.

Pros
  • Very long-lasting, capable of over 8,000 cycles
  • Very compact and lightweight design
  • Easy to use in sequence for even more power
Cons
  • No battery management system
  • No battery performance display

5. RUIXU Lithium-Iron Phosphate Battery Pack

Last update on 2024-01-30 / Affiliate links / Images from Amazon Product Advertising API

Finally, we have a lithium-ion battery pack manufactured by RUIXU.

As the name implies, this is not a singular battery but a pack of four separate cells that can be connected to make one battery.

Aside from the individual cells, the manufacturer also provides you with the means to connect them all.

The benefit of this is that you can choose to use the individual cells for different things that don’t need as much power if you want.

Because the individual cells can come apart, this can potentially make it easier to transport and store this battery.

It’s not the most long-lasting of the batteries on this list, however, being capable of around only 2,000 charging cycles.

Nonetheless, this still means that you’ll be able to get a fair amount of use out of this battery pack.

Weighing in at a combined total of 15 kilos, this battery pack is a little on the heavier side, but not so heavy as to make it very hard to transport.

Pros
  • The separate cells make it a more versatile package
  • Affordable price
  • Suitable for a variety of different power generating and storage applications
Cons
  • Battery life may be a bit short compared to other batteries

Our #1 Pick For RV Solar Power
