How to Choose the Best Battery Monitor for RV?

Before buying or choosing a battery monitor for your RV, you need to consider the following things:

Current range

Checking the current output is important as it ensures that the given battery can set up all the appliances without running out of power. Gladly most of the battery monitors allow you to check the output of your batteries.

The entry-level battery monitors will only read 0 to 100 amps. But higher-level battery monitors will read up to 500 amps. 

Voltage range

Even if your RV batteries offer you a high current output, they might not be compatible with all electronic devices. For this reason, you should check the voltage of the batteries.

Some of the most common battery voltage ranges include from 6.5 to 70 volts, 6.5 to 100 volts, 10 to 120 volts, and sometimes even 0 to 200 volts. 


Not all battery monitors come with the same display size and same backlight color so choosing one that comes with a great display is a better option. 

Bluetooth connectivity

For checking the readings of the battery, the easy and the most comfortable way is to use the display but many find this difficult to use. To tackle this issue, some battery monitors now come with inbuilt Bluetooth features. And this allows you to check your battery readings straight from your phone. 


The price of the battery monitor is also an essential feature in choosing the best battery monitor for your RV. Here you have many options. If you want a battery monitor that comes with many features, then you need to spend more. But if you want a battery monitor that comes at a lower price, then you need to be limited with the features. 

Ease of usage and installation

No one wants a complicated installation process. You need to choose a battery monitor that is easy to use and easy to install. That’s why these three RV monitors come highly recommended.

Temperature sensors

Temperature is the key factor that affects the condition and performance of your batteries. If your battery monitor comes with temperature sensors, you can keep an eye on undercharging and lower charging, increasing and decreasing the battery’s temperature. For your convenience, some of the battery monitors will allow you to read the temperature in Celsius and Fahrenheit. 

History of data

This essential feature needs to be checked while choosing the best battery monitor for your RV. With this feature, it is easy to make decisions using the data stored in the battery monitor. The battery monitor will store the electrical power data, total discharges, and the number of charging cycles.

No one wants a battery monitor that comes with less warranty. Sometimes if your battery monitor fails to work, the warranty will make the job easy for you as there is no need to spend money on the malfunctioned part which is why a warranty is a great option.

Most of the battery monitors come with one year or three years or five years warranty. Choose a battery monitor that comes with the highest warranty period. 


There you have it! These are the Best RV Battery Monitors (Top 3) available online. If you want to prevent any miscalculations or if you want to take note of the charges and discharges, then a battery monitor will do the work for you.

Whether you are a pro RVer or a newbie, it is always advised to use a battery monitor in your RV to prevent any dangers and enjoy a safer vacation.

It’s nice to come across articles such as this one. As a woman, I am really not well-versed on technical, mechanical, or electrical stuff. I see these things as part of a man’s world. But we do need to learn about these things as women, most especially that I am single and have to do most things by myself.

Mandy @ Money Mending

This is very detailed! Thank you for taking the time to fully educate us in this post.


I never realised that the world of RV batteries would be so complex. I’m not sure I will ever own or use an RV but if I do, I’ll certainly come back here for more information.

I admit that these products are not the ones I use but I appreciate your advice!

very useful! You gathered tons of information in one place so I don’t have to do it by myself.


That was wonderful information and good general knowledge about RV battery monitors explained in detail. It’s true RV relies on battery the most and hence very important to keep them charged.


Good stuff! Thanks for sharing. This info comes in handy.


This is helpful since I have no idea on how to choose the best battry monitor. Thank you for sharing these tips. Happy to know that some monitors already have bluetooth features which allows us to check the readings through our phones. That’s just simply convenient.
