Custom And Modified

As the name suggests, a custom or adapted battery box comes from standard versions. The consumer has still modified it to include such functions, such as a locking mechanism or a basic ventilation slot.

Buying Guide For The Best RV Battery Box

Battery boxes may sound like a straightforward product initially, but identifying the perfect one for your requirements maybe even more complicated than anticipated.

If you’re still unsure which of the better RV battery packs is for your rig, our purchasing guide below has the answers.

Size Of The Box

Size is a crucial factor when selecting the right RV battery pack for your rig. The box should be big enough for the battery to fit inside but not so large that there’s space for them to travel about during shipping.

Some battery packs are compatible with a range of battery pack sizes and can come with a flexible divider to keep them steady if they’re a little short in the case. Each model should clarify the size of the battery they are appropriate for, so be sure to double-check the specs before purchase.

Weather Protection

If your RV battery box is installed outside of your vehicle, you may need to protect it from the elements. Batteries can be destroyed by water, UV rays, debris, and high temperatures. Still, based on your behavior, you’ll have to verify that your RV battery pack can handle these obstacles.

Just about all plastic RV battery boxes would be waterproof, but some versions will have lid vents to allow water during heavy rain. Therefore, if you’re traveling in regions with a rainy environment, it’s safer to look for a battery pack with drainage holes to keep the water out.

Any RV battery boxes have been tested for resilience and shattering at a range of temperatures. If you live or fly to places with harsh temperatures, these are the best choices.

The same happens to UV protection ? heavy sunlight will degrade and fade your battery box, reducing your battery’s amount of security. If you spend a lot of time in desert states, you should always search for a built-in UV defense model.


The cost of RV battery boxes ranges significantly across the spectrum of existing options. Any of the considerations that can affect the cost are the building materials, whether they have been tested for reliability or whether they come with any extra features or accessories.

That said, the most costly RV battery box isn’t exactly the best one for your needs. Reliable and robust battery boxes can be found in the price range of >$30, while more specialized models can cost as much as $50 and up.

Mounting Options

RV batteries are relatively massive, but when you pick your enclosure, make sure it’s sturdy enough to support the mass of your batteries when you’re assembled.

Many versions come with some keep-down braces and other hardware mounting attachments to help you safely attach the package. This is necessary to ensure that the battery does not change too far during transport.

Easy To Install

The perfect RV battery box for you was the one that was easy to mount without as much time and difficulty.

Some of the battery boxes will come complete with all the mounting hardware you need for a comfortable fit, but some cheaper brands do not.

Anyway, the installation directions should be simple and concise, so you can be confident that you’ve mounted it securely and properly before you reach the path.


The cover on your battery box should be securely placed and secured to ensure that it is well covered during travel and in poor weather.

But it’s also expected to be quick enough to open without trying. Such crates have locking latches, while others are kept in place with sturdy nylon belts and clasps.


The batteries are very large, and lugging them from location to location can be a bit of a strain. To make this job less challenging, we suggest that you search for a lightweight RV battery box that includes a sturdy, convenient handle for easy transportation.

Such versions have handles, while others may have ergonomic hand handles molded to the arms. The right choice would depend on our expectations for you.

Smart Features

More costly RV battery boxes can come with extra smart features, such as LED battery chargers, 12V outlets, and USB ports so that you can charge your devices off-grid.

Battery charge meters are especially helpful because they allow you to monitor your battery’s remaining charge without committing to speculation. Usually, the residual charge is reflected through the LED light panel by pressing a button.

USB ports and 12V outlets help charge your mobile phone and electronics if you don’t have a battery hook up, but because most RV owners can also carry a power pack onboard, you’ll have to consider this function is worth the extra cost.


RV batteries aren’t inexpensive, but, sadly, they’re a perfect target for criminals trying to make a fast buck.

Although every RV battery boxes are sealable, they serve as a barrier to robbers. When tied down and safely mounted, a robber would not be able to steal away your precious battery in the blink of an eye. They’re going to have to put some time into it first, thereby raising the probability that they will attract attention to themselves.

That said, whether you live or plan to fly in an environment that has a history of robbery or want more peace of mind, we suggest that you select a lockable battery box for maximum protection.
