Step 1: Gather All Necessary Equipment

Before you start connecting the batteries, make sure you have all the required equipment. This includes the four 12V batteries, battery cables, a wrench, a battery tester, and safety gear like gloves and goggles.

Step 2: Choose a Suitable Location

Select a well-ventilated and dry location for setting up your battery bank. Avoid areas with extreme temperatures, as batteries perform optimally in moderate conditions.

Step 3: Arrange the Batteries

Position the batteries close together, ensuring easy access to all terminals. This will make the connecting process smoother. [how to connect four 12v batteries to make 48v]

Step 4: Connect in Series

Join the positive terminal of the initial battery with the negative terminal of the second battery. Repeat this process for the third and fourth batteries. This creates a series connection, effectively adding the voltage together.

Step 5: Connect in Parallel

Now, take a battery cable and connect the remaining positive terminal of the first battery to the positive terminal of the fourth battery. Similarly, connect the remaining negative terminal of the second battery to the negative terminal of the third battery. This creates a parallel connection, allowing the system to handle higher current demands.

Step 6: Double-Check the Connections

Carefully inspect all connections to ensure they are secure and properly tightened. Loose connections can lead to inefficiencies and safety hazards.
