Do They Make a 24V Marine Battery?

24v marine battery

You’re probably familiar with the standard 12V marine battery. Perhaps you’ve even used this type of battery to power your trolling motor, your lights, or other electrical systems on your boat.

But is the 12V battery your only option? Is there a larger battery, a 24V battery, that could be used to power more systems or larger trolling motors?

In short, do they make a 24V marine battery?

Can this type of battery be used for trolling motors?

What are some of the best 24V marine batteries on the market?

And what are some alternatives for using a 24V battery?

Great questions! In this article, we’ll spend some time exploring the answers and discussing everything you need to know about 24V marine batteries.

Do They Make a 24V Marine Battery for Trolling Motors?

The first and most obvious question is whether they even make 24V marine batteries. Is such a battery available on the market, and can you use it for your trolling motor?

The good news is yes, 24V batteries do exist and are widely available for purchase. 

24V deep cycle marine batteries are the best option for trolling motors and many other marine applications, as they can be deeply discharged again and again without sustaining damage. 

So, why use a 24V battery? Let’s talk about some reasons why you may want to invest in this type of battery in the first place.

  • You have a large trolling motor: Some large or complex trolling motors, such as Minn Kota’s Ulterra model, have 24V systems. To be able to use these types of trolling motors, you will either need multiple smaller batteries or a single 24V battery.
  • You are running multiple systems off one battery: Even if you only have a 12V trolling motor, you may have other systems you would like to power off a single battery–fishfinders, for example, or lights or radios.
    Having a larger battery will enable you to power more electrical systems off that one battery, which in turn will free up more space in your boat.
  • You want to save space: If you have to use multiple smaller batteries to get the same amount of power as you would get from one 24V battery, then all those extra batteries are going to take up a lot of space.
    On the other hand, if you use just one 24V battery, you will have more room in your boat for storing other items.

Sounds pretty good, right? But are there any drawbacks of 24V batteries? Let’s take a look:

  • They are expensive: As you might expect, 24V batteries cost quite a bit more than 12V batteries.
    This is, of course, due to the extra voltage and the fact that they are larger than 12V batteries, but it is also because most 24V batteries are lithium iron phosphate batteries. These are some of the highest-quality batteries you can get, but they are very costly.
  • There are fewer options available: As noted above, most 24V marine batteries are of the lithium iron phosphate type. What if you want a 24V lead-acid, AGM, or gel battery instead? These are available, but you may have to search a little harder to find them.

Alternatives to 24V Marine Batteries

So, what if you don’t have a 24V battery and don’t want to spend the money for one? Are there any ways to meet your boat’s power needs without one?

The best alternative to buying a 24V battery is to use two 12V batteries. If you don’t have them already, you can sometimes save money by buying them in 2-packs 

But what are the benefits of using a pair of 12V batteries over a single 24V battery? Let’s find out:

  • 12V batteries save money: You can buy a 2-pack, as noted above, but even if you buy them separately, investing in a set of 12V batteries often costs less than investing in one 24V battery.
    This is because they are smaller and generally cheaper to make, and you can find many different kinds of 12V batteries–including lead-acid, the cheapest kind–quite easily.
  • They give you more options: While most 24V batteries are of the expensive lithium variety, 12V batteries are readily available in all types–lead-acid, AGM, gel, and lithium. You can easily choose whichever type fits your needs and budget.
  • They work just like a 24V battery: When wired together in series, two 12V batteries will produce the same amount of power as one 24V battery. There is no need to worry about whether they will work as well as a 24V battery because they will work in the same way.

So now you may be wondering, what are the drawbacks? Nothing in life is perfect, so why might it be better in some cases to choose a 24V battery over two 12V batteries? Let’s take a look:

  • Two batteries will take up more space: 12V batteries are a little smaller than 24V batteries, but having two of them will still take up significantly more space in your boat or battery compartment than a single 24V battery would.
  • There is more wiring involved: As noted above, 12V batteries must be wired together in series. While there are plenty of tutorial videos to help you learn how to do this, some boaters may find it easier to skip this step by installing a single 24V battery.
