Recap: The Best RV Battery Monitors

Buying a New Battery Monitor: What to Look For

When choosing an RV battery monitor, there are some factors that you should keep in mind. Depending on your situation, these factors’ details may vary, but they are of equal importance. Durability, accuracy, compatibility, and the installation process affect a battery monitor’s overall quality and should come first when you are putting together a priority list.


A device that monitors your RV battery should be able to withstand whatever an RV goes through daily. When it comes to this, choosing the one that suits your lifestyle is essential. Suppose your travels bring you to places with lots of inclement weather, for example.

Regardless of where you need to position a battery monitor, there is a viable option out there. Weather and waterproof monitors allow you to place them outside if that works best for your setup.

If you need it inside, there are models that you can set out of the way of high traffic areas. Ensuring that the battery monitor you choose is suitable for exposure to whatever conditions you may come across.


One of the most vital aspects of a battery monitor is its accuracy. The whole point is to know the status of your setup, after all. A reading that is not accurate is not only unhelpful, but it can be detrimental to your system.

One aspect of RVing is that mostly everything runs on batteries. These batteries can start to depreciate over time, especially with improper maintenance. Accurate evaluations from a battery monitor of your available Amp hours are integral for caring for these batteries. Even a minute error in the reading can cause oversight during maintenance time.

Accuracy is also vital for maintaining any refrigeration hookups that you have, allowing food to stay safe. Keeping the ambient temperature at a comfortable level can be helpful, too. A battery monitor helps you keep on top of any sudden changes to address them immediately.


To ensure that you get a battery monitor that will work with your system, you must know the current system’s specifics. These technical details will help you figure out which monitors to focus on during your search and which ones not to bother with. Having all the correct attachments, wires, and tools before starting will save you from a lot of headaches.

Some of the time, battery monitors do not come with the wires or shunts you need to install them. In that case, you must carefully determine what else you will need while deciding on the battery monitor that suits your situation. A battery monitor will not set up or work properly, if at all if there are any incompatible connections or accessories.

We also really like smart monitors that have Bluetooth connectivity and other features that can connect to your phone and other tech in your camper.

Easy to Set Up

Sometimes, setting up a battery monitoring system can be complicated and frustrating. This confusion is why finding one with clear instructions is critical, especially for those still unfamiliar with the process. There are many wires, and putting one in the wrong place will cause the monitor not to work.

If it is hard to decipher the directions, you may become frustrated and either give up or do something incorrectly. In the end, this helps no one and gets you no closer to having a way to see your power usage. Either ensure that the instructions are clear, that you can get clarification if needed, or have someone else around to help put things together.

You may need additional mounting supplies or even shunts and wires to complete the process, depending on what the monitor you chose has in the box. It is critical to know what you need and have what you need for a smooth installation process. If not, you may run into problems before even getting a chance to begin.

Frequently Asked Questions

How Do I Monitor My RV Battery Level?

One of the best ways to monitor your RV battery level is with a battery monitor. There are a ton of different types of battery monitors, including ones that connect to your “smart” system for easier monitoring.

What Does A Battery Monitor Do?

Battery monitors check the amps coming into and going out of your battery, and can help you monitor the exact level of your battery without having to connect it to a reader. Most battery monitors show voltage as well as the level of the battery so you can easily determine its charge level and how much “pressure” is being put on your battery while you are running different items in your RV.
