Why an RV Double Battery Box is Necessary

As an RV owner, I know how important it is to have a reliable power source. When you’re on the road, you can’t always rely on campground power, and you may need to run your RV’s appliances for extended periods of time. That’s why I invested in a double battery box.

A double battery box is a simple but effective way to increase the capacity of your RV’s battery system. It’s basically a metal box with two battery compartments, and it’s wired in parallel to your existing battery. This means that the two batteries work together to provide twice the power of a single battery.

There are a number of benefits to having a double battery box. First, it gives you more power to run your RV’s appliances. This is especially important if you’re planning on doing a lot of boondocking (dry camping), where you won’t have access to campground power.

Second, a double battery box can help to extend the life of your batteries. When you’re only using a single battery, it’s constantly being drained and recharged. This can shorten the battery’s lifespan. With a double battery box, the batteries are shared, so each battery is only drained and recharged half as often. This can help to extend the life of your batteries by up to 50%.

Third, a double battery box can provide backup power in case your main battery fails. This is a valuable safety feature, especially if you’re in an area where you can’t easily get help.

If you’re an RV owner, I highly recommend investing in a double battery box. It’s a simple and affordable way to increase the reliability and longevity of your RV’s battery system.
