How do I connect batteries in series?

To connect batteries in series, start by confirming all batteries have the same voltage and capacity. You'll connect the positive terminal of one battery to the negative terminal of the next. This setup increases your total voltage while maintaining the amp-hour capacity.

What is a series battery connection?

When you connect batteries in series, you fundamentally increase the total voltage while keeping the same amp-hour capacity. In a series connection, you link batteries by connecting the positive terminal of one battery to the negative terminal of the next. For example, two 12V batteries will give you a total voltage of 24V.

Can a battery be connected in series?

When connecting batteries in series: Never cross the remaining open positive and negative terminals with each other, as this will short-circuit the batteries and cause damage or injury. The other type of connection is parallel. Parallel connections will increase your capacity rating, but the voltage will stay the same.

Is it safe to connect batteries in series?

Yes, it's safe to connect batteries in series as long as you follow some important guidelines. Make certain all your batteries have the same voltage and amp-hour ratings, and always connect the positive terminal of one battery to the negative terminal of the next.

Should you wire a battery in series?

When you need more voltage than a single battery can provide, wiring batteries in series is a popular and effective solution. By connecting multiple batteries in series, you can increase the total voltage while maintaining the same current capacity.

Should you connect batteries in series or parallel?

Connecting batteries in series or parallel allows you to increase the voltage or current capacity of a battery bank. Understanding the difference between these two configurations and how to properly wire them is key for building battery banks for energy storage systems, RV/boating applications, solar setups, and more.
