    Buyer’s Guide to Buying the Best RV Battery Monitor

    When you are out camping, it is a good idea to have a battery monitor with you that will show you the status of your battery. You don’t want your battery conking out in the middle of nowhere, now do you? A battery monitor is a system that measures the flow of energy in your battery all the time. Several other measurements and factors that are important in calculating the amount of charge present are also shown by a battery monitor.

    It is a useful tool for your campervan that you should have. There are various products on the market, and each seems to be perfect. However, that is not the case. Some various features and factors set a battery monitor for campervan apart from each other. Let’s take a look at the things you need to keep in mind before you go out and buy a battery monitor. Let’s get started.

    Types of battery monitors

    There are two kinds of battery monitors for RVs and campervans. The first kind of battery monitor measures only the voltage and is commonly known as a voltmeter. The other type is the one that measures both amperes and volts. Voltmeters are a simple and cheap option and measure the voltage of your battery in an easy way. If you know how to read the state of charge of your battery depending on their type, e.g., AGM batteries, marine battery, Lithium-Ion, etc., then you are good to go with a voltmeter.

    However, the issue with voltmeters is that the reading will not tell you anything about how much power that is being drawn by the system, If you are charging the battery with the help of solar power from solar panels (from your solar system with solar panel) or alternator, the voltmeter will not tell you whether your battery is being charged or not.

    This means that you can miss out on faults and end up with a damaged battery. Batteries don’t come cheap, and if you are not careful, you are going to end up losing hundreds of dollars. Therefore, you should buy a proper RV battery monitor also like has an “ammeter” functionality rather than buying a simple voltmeter. Some come as multi-meters while others as voltmeters. You can choose the type of monitor as per your preferences and requirements.


    The size and quality of the monitor’s display have a considerable impact on how much information it can provide. Some are incredibly rudimentary, providing nothing more than a charge level or voltage.

    Though some devices employ basic numeric displays, the majority of units include LCD and LED panels that may be put in your RV. You’d appreciate being able to read the voltage, power, and current all at once. Isn’t it just so simple? The parameters may be simply programmed to track the remaining battery capacity and other parameters.

    Another successful model has an appealing display and includes a solar charging read-out. This is great for individuals who have an expensive solar battery or controller. For a more viewable display, screens range from blue to neon green. It can also be used as a nightlight because it only uses a small amount of power. They can provide detailed data on charge level, battery temperature, voltage, charging pace, and much more. It will cost extra, but if you want to effectively monitor the state of your battery bank, we believe it is well worth it.

    Mobile App

    Monitoring software that works with apps. You go from having to be physically present to monitor the battery state of your RV to being able to check it from anyplace you have cell service. This is really useful when checking your RV’s batteries while it is in storage. Simply connect the monitor to your home WiFi and you can check the status of your RV without having to open it.

    Compatibility with existing electrical systems

    You need to check out if the battery monitor you are buying is compatible with the existing electrical system in your van build like solar panels. Various battery monitors are compatible with different kinds of electrical systems, so make sure you check this before purchasing the final one. Theses systems work with various voltages. They work with different battery type as well, such as SLA, lead-acid, NiCad, gel cell, etc.

    Power consumption

    With the help of battery monitoring, you can check if your charging equipment is working properly or not. You can also know which equipment is wasting how much power or consuming additional power. If you become aware of this, you can turn it off to save your battery charge.


    RV Battery monitors come with notification alerts. They notify you when your RV battery is dying, or if it is not charging properly. You can also record the previous data of the battery and use it if you are doing troubleshooting.

    Basic battery monitors display the voltage and perhaps current of your batteries, but more complex models may store messages and even send alarms. They’re especially beneficial if you’re going to store your RV and want to be able to check for low voltage warnings or other difficulties on a regular basis.

    Temperature Sensor

    A few battery monitors not only show the battery status in the form of amp meter and volts, but they also show the battery temperature using temperature sensors. This is an important feature with the help of which you can keep the temperature of your battery under control and prevent it from overheating. The LCD displays of the battery monitors tell you everything you need to know about the health of your battery.

    Ease of Use

    Nothing irritates us more than unnecessarily complicated gear. Battery monitors are designed to deliver a few bits of vital information and should not require a 30-page handbook to set and use.

    In terms of usability, seek for streamlined controls with an easy command scheme. As previously stated, we suggest app support for larger/more sophisticated battery systems because it makes them much easier to operate.

    Battery Shunt

    A battery shunt is a vital component that allows a battery monitor to function properly. It attaches to your battery, normally on the negative wire, and allows the monitor to read voltage, current, and other parameters.

    Some battery monitors have a battery shunt, but others do not. Check to see if a shunt is available for your chosen battery monitor, as some manufactures employ unusual proprietary connectors.


    When it comes to any product, warranty is something you can’t skip on. A good and long warranty period assures that the manufacturers have complete faith in the quality of their product.

    Check the warranty period of the batter monitor so that if the device fails you, you can get a refund or get it repaired at least. You should also take a look at the customer services of the company so that if you have any queries in the future, you will get a quality response.


    When you are out buying not only battery monitors, you have to keep an eye out for the price tags. A higher price tag is not a guarantee that you will get better quality as well. Many battery monitors come at an affordable cost and function correctly.
    Additional features result in added costs.

    Be certain that you know what features you are looking for in a battery monitor, and then buy one that suits your budgetary requirements. Fix a budget, write down the features you want in your battery monitor, and then choose the one that fulfills both criteria.

    Frequently Asked Questions

    What is a RV battery monitor?

    The first thing that you need to know is what a monitor is actually. It is a device that gives you detailed information regarding the charge and load on the battery. Moreover, it also monitors the number of cycles a battery goes through along with the battery history. Battery monitoring your when you are in a van is pretty important since you are out on the road and don’t want to end up with damaged batteries.

    A battery monitor has an ammeter functionality. It analyses the amount of current that is flowing in and out of the terminals of the battery to give you the output. It requires that all the grounded wires are ground on a shunt that is, in return, connected with the negative terminal of the battery. A connection is made between the battery and the shunt directly with no connections with the positive terminal.

    The shunt is the brain of the battery monitor. The interface panel is plugged with the shunt. Voltmeter also performs a similar function. However, it lacks various features that are offered by battery monitors.

    Why do I need a RV Battery Monitoring System?

    A battery monitoring system always measures the amount of time your batteries enter and leave. These measurements are used to calculate the state of charge or discharge of your battery. BMS acts as a fuel gauge for your batteries. Also very useful for measuring the exact amount (MPS) of the instruments that each piece of battery monitor uses. Strengthen the instruments and watch the current value change.

    A BMS can tell you how much power is entering or leaving your batteries at any given time. What percentage of the total capacity of your battery is available. How much time is left before your battery is fully charged or discharged. Some conditions allow you to set alarms to turn devices on or off when certain conditions are met. For example, you can start a generator automatically when your battery is less than 50%.
