# How to Connect 2 12V Batteries to Make 24V

Are you wondering how to create a 24V battery system? Maybe you’re working on an RV, boat, or solar power project and need a higher voltage than a single 12V battery can provide. Fortunately, connecting two 12V batteries together in series can create a 24V battery bank. In this article, we’ll walk you through the steps on how to connect 2 12V batteries to make 24V.

## How do you make 24 volts using two 12 volt batteries?

To make 24 volts using two 12 volt batteries, you need to connect them in series. This means that the positive terminal of one battery is connected to the negative terminal of the other battery. The remaining positive and negative terminals of the two batteries become the positive and negative terminals of your 24V system.

Here are the steps to connect two 12V batteries to make 24V:

1. Gather your materials: You will need two 12V batteries, battery cables, and a battery charger.
2. Ensure the batteries are the same: It is important to use two identical 12V batteries to create a 24V system. Mismatched batteries can lead to uneven charging and discharging, reducing the lifespan of the batteries.
3. Connect the batteries in series: Use battery cables to connect the positive terminal of the first battery to the negative terminal of the second battery. The remaining positive and negative terminals will be your 24V output.
4. Charge your batteries: Use a 24V charger to charge your battery bank.

## What happens when you connect two 12 volt batteries in parallel?

Connecting two 12V batteries in parallel means that the positive terminals of both batteries are connected together, as are the negative terminals. This creates a 12V battery bank with twice the capacity of a single 12V battery. However, it does not increase the voltage.

## Can you charge 2 12V batteries with 24V?

No, you should not charge 2 12V batteries with 24V. The voltage of the charger should match the voltage of the battery bank. Overcharging a battery bank can lead to damage or even explosions. Always use a charger with the correct voltage for your battery bank.

## What happens if you connect 12V battery to 24V?

Connecting a 12V battery to a 24V system can cause damage to the battery and any connected devices. The higher voltage can cause the battery to overheat, leak, or even explode. Always double-check your voltage when connecting batteries to prevent damage to your equipment and yourself.

In conclusion, connecting two 12V batteries to make 24V is a simple process that can provide the power you need for your next project. Just remember to use identical batteries, connect them in series, and use a charger with the correct voltage. And always double-check your voltage to prevent any mishaps.
