What is a battery monitor for RV?

Living in an RV means you have to rely on battery power. Whether you’re a weekend/holiday RVer or a full-time RVer, you still need to run on batteries, and being able to monitor your battery status is always helpful.

An RV battery monitor is a device that helps you keep track of the amount of power that goes into and leaves your RV battery. Without a battery monitor, knowing how much power you have left in your RV battery often requires regularly checking how many Amp-hours are used. This is a rather tricky and inconvenient means.

Battery monitors make it easy to know what goes on with your battery; how much power you’re using at any given time and how much energy you have left, through a simple screen. Most of them have the option to let you connect to your smart devices, making it easy to monitor your RV battery wherever you are. RV battery monitors work like a fuel gauge for your batteries. It is an essential device for every motorhome owner.

How do RV battery monitors work?

An RV battery monitor works by measuring the exact current flowing in and out of your battery.

It does this through a very accurate shunt. The shunt is what regulates the current flow, and is kept in between your battery bank’s negative terminal and everything connected to it.

It usually has a small data port to allow you to plug in the cable that runs to the monitor, along with a small power wire that supplies power to the monitor. The battery monitor is a small display screen.

Once the monitor detects that your battery is full, it keeps a record of every amp of current outflow and displays to you in the form an easy to read empty to a full bar graph, a percentage of battery power remaining.

This information then gives you a utilizable ‘gas gauge’ view of the condition of your batteries. RV battery monitors usually come with a mobile app that makes it easy to monitor your RV battery very conveniently.

What are the different types of RV battery monitor?

There are two kinds of battery monitoring devices for RVs. One is commonly known as a voltmeter and works by measuring only the voltage—the other kind measures, both voltage, and amperes.

While voltmeters are more straightforward and cheaper, its readings don’t tell you anything about how much power is drawn by your RV system. It also doesn’t tell you whether your battery is charging or not when you use solar power or alternator charge methods. Not knowing this means that you could miss out on faults and end up with a damaged battery, which can be frustrating considering how expensive RV batteries are.

Buying an RV battery monitor that reads amperes is always more convenient. This type comes in different kinds, most of which can be installed into your RV battery system. Most modern RV battery monitors of this nature include an LCD and other new upgrades. Some come with temperature sensors and Bluetooth as well.

Why do you need a battery monitor for RV?

Having all an RV battery monitor gives you all the benefits of having a battery monitoring device and more. An RV battery monitor allows you to estimate battery capacity, prevent over-discharge, know when your batteries are charging, and be aware of any faults your battery may develop.

Investing in a good quality RV battery comes with many extra benefits such as text alerts when something goes wrong. This feature alone could save you a lot of stress and money because knowing about a fault as quickly as possible always helps in solving it.

Having a modern RV battery monitor can also help you protect your food. For instance, with the help of the information given by these devices, you could find out beforehand if your fridge is not working. It could also notify you if the temperature of your fridge drops or remains constant for too long. This helps you stay ahead and take care of little refrigeration problems right away.

Models that come with temperature sensors help you to maintain the interior temperature once you set it. You could go out and leave your pets in your RV, rest assured that your pets are safe from extreme temperatures. If the temperature rises, you also receive a notification to help you fix the problem right away.
