12V Vs 24V: What’s the Difference in Battery System?

What are 12V Battery Systems?

In order for you to choose the best battery setup for you and your personal circumstances, let’s first look at the two main battery systems you are likely to need.

A battery system, as the name implies, is a set of batteries which have been connected together in order to provide power in an electrical form. Needless to say, the two most common types of battery systems are a 12v battery system and a 24v battery system.

While we use batteries for all kinds of different reasons, and indeed, all kinds of different batteries, 12v batteries are the most common when used with DC (Direct Current) power systems. You’ll find these most commonly used with boats, off-grid power systems, RVs, and other forms of vehicles used for daily transport.

If your power requirements are 3000W or below, you should find that a 12v system is sufficient enough in terms of power needs.

The main reason why a 12v battery is so commonly used in electric vehicles is down to the fact that most of the components found in vehicles have been specifically designed to operate on a 12v battery. 12v batteries provide 12 volts under a nominal load. Most electrical components in vehicles, such as the ignition, lighting system, and starter system have been designed specifically to run off of 12 volts.

As you might have guessed, 12v systems are noticeably smaller than a 24v battery and they therefore take up far less space. What a lot of people don’t realise is that the 12 volts is not a solid figure. Some 12v batteries offer a slightly lower voltage, whereas others offer a slightly higher voltage.

Although most vehicles use 12v batteries, you will sometimes find larger vehicles using a 24v battery instead. Large trucks, bigger boats, construction vehicles, and busses may sometimes use 24v battery setups due to the additional power requirements.

What are 24v Battery Systems?

Now that we’ve looked at what a 12v battery setup is, as we are looking at 12v vs 24v batteries we’d better now take a look at a 24v battery system.

As you have probably already figured out, a 24v battery provides 24 volts of power, as opposed to 12. Under the nominal load, these batteries produce 24 volts.

Some people will create 24v by simply running two 12v batteries. By far, the most efficient way of producing 24v however, is to purchase a 24-volt battery from a professional and reputable battery supplier.

24-volt batteries are less common than 12-volt batteries. They offer a higher voltage, so the current is reduced. This means that they generate less heat and they waste less power as a result. Because they are larger and more powerful, they’re used in larger, more powerful vehicles which require more power.

Put simply, the greater your power demands, the more beneficial a 24v battery is likely to be.

What are the Benefits of 12V Batteries?

To help compare the key differences in terms of 12v vs 24v battery systems, we’re going to explore some of the key differences between the two and look at the benefits each type of battery provides

First off, we’ll look at 12v batteries:

Takes up less space

One of the main reasons why so many battery supplier businesses are seeing such a high demand for 12v batteries is down to the fact that they’re smaller and take up less space.

A 12v battery is much smaller than a 24v battery, and is also lighter. This makes it much more convenient. If you’re using it in a smaller vehicle such as a boat or an RV, where space is limited, a 12v battery will be more convenient as it will take up less space, leaving you with more free space.

As it is lighter, it will also reduce fuel consumption and improve power and performance as well.

Compatible with more vehicles

Another of the key benefits associated with using a 12v battery is the fact that it will be compatible with more vehicles.

As previously mentioned, most vehicles have electrical components which have been designed to be compatible with a 12v battery. Because 12v batteries are compatible with more vehicles, this reduces the risk of you running into issues when it comes to matters relating to powering your vehicle.

Ideal for lower power setups

If you’re operating a lower power setup of below 3000W, you’ll find that a 12v battery is more than sufficient for all of your powering needs.

In RVs for example, you’ll find that most typical RV appliances requiring power, I.E the shower, refrigerator, and lighting setup, will work perfectly fine with a 12v battery setup. You’ll find that only one battery is needed to comfortably power your RV.

Basically, if your power needs are below 3000W, you’ll find that a 12v battery is more than sufficient.

More affordable

Finally, when talking about a 12v vs 24v battery, we also need to ensure we take price into consideration.

Generally speaking, 12v batteries are much more affordable than 24v batteries. 12v batteries require less power, and are also much easier to come by in comparison to a 24v battery, which can be difficult to source.

What are the Benefits of 24V Batteries?

Now let’s look at how 24v batteries stack up in terms of benefits:

Ideal for higher power setups

If you’re running a vehicle requiring more power, or if you simply have a higher power setup, I.E an off-grid setup, you’ll find that a typical 12v battery just won’t do the job.

12v batteries are fine for setups requiring less than 3000W, but what about vehicles and setups requiring more than 3000W? Well, then a 24v battery may be required.

Sure, they may be larger and take up more space, but they will provide considerably more power.

Ideal for solar

Even though we just looked at how 24v batteries are ideal for higher power setups, we feel it pertinent to look at solar in more detail.

As more people choose to have solar panels fitted, a 24v battery is much more beneficial when used for solar, as opposed to a 12v battery.

If you were to use a 50 amp rated charge controller on a 24v battery, you’d find that you can connect this up to 1400w of solar panels. Connect it to a 12v battery however, and you can only connect to 700w of solar panels.

With a 24v battery, you require half the amount of solar charge controllers. Not only that, but the solar setup will also operate more efficiently running off of a 24v battery.

Reduced wiring costs

Another benefit of 24 volt batteries in terms of 12v vs 24v batteries, is the fact that 24v batteries can greatly reduce your wiring costs.

As 24v batteries require less wiring, this means less cable and far cheaper wiring costs. Not only that, but they are also more efficient and offer less resistive losses.
