How to Create a 24V System using Two 12V Batteries


In various industries, it is often necessary to have a 24V power system for specific applications. To accomplish this, you can create a 24V power supply by connecting two 12V batteries in series. This article will guide you through the process.

Step 1: Choosing the Batteries

When selecting batteries, ensure they have the same capacity and chemistry. This will ensure a balanced discharge and charging pattern. It is also important to consider the physical size and weight of the batteries, as well as their compatibility with your device or application.

Step 2: Safety Precautions

Before proceeding, ensure you follow safety precautions, such as wearing protective gloves and safety glasses. Disconnect any power sources and double-check polarity to avoid short circuits. Take extra care when working around electrical equipment.

Step 3: Connecting the Batteries

To create a 24V system, connect the positive terminal of the first battery to the negative terminal of the second battery. Use proper battery connectors and ensure a secure connection. This series connection increases the voltage while keeping the total capacity unchanged.

Step 4: Voltage Monitoring

To ensure the longevity and optimal performance of the batteries, it is essential to monitor the voltage regularly. Invest in a good quality multimeter and check the voltage regularly to identify any discrepancies or imbalances.

Benefits of a 24V System:

1. Efficiency: A 24V system allows for reduced current flow, resulting in lower resistive losses and enhanced overall efficiency.

2. Compatibility: Many industrial equipment and devices require a 24V power supply, making it a widely compatible voltage level.

3. Longevity: As a 24V system distributes energy more uniformly, it prevents excessive stress on individual battery cells, thus prolonging the battery lifespan.

4. Wiring Costs: By using a higher voltage system, you can decrease the size of conductors, resulting in cost savings on wiring materials.

5. Power Availability: A 24V system can provide higher power availability, enabling it to drive motors, actuate solenoids, and operate various other power-hungry applications.


Creating a 24V power system from two 12V batteries is a straightforward process. By following the steps outlined above and considering safety precautions, you can harness the benefits of a 24V system. Whether it is for industrial, automotive, or renewable energy applications, a 24V supply offers compatibility, efficiency, longevity, and cost savings. Remember to regularly monitor the voltage to maintain optimal battery performance.
