A Complete Diagram: How to Connect 2 12 Volt
Learn how to connect two 12 volt batteries in series with this detailed diagram. Increase your voltage output for a more powerful electrical system.
There are three different ways to connect batteries together, each with its own outcome. Connect in series - Connecting two or more batteries together in series will increase the overall voltage. For example, if you connect two 12V 75Ah batteries in series, you will have a battery voltage of 24V and a capacity of 75Ah.
Wiring two batteries in series involves connecting them end-to-end so that the positive terminal of one battery connects to the negative terminal of the other. This arrangement results in an additive voltage output while keeping the current constant throughout the circuit.
To connect batteries in series, you need to connect the positive terminal of one battery to the negative terminal of the next battery. Repeat this process for all the batteries in the series. The positive terminal of the first battery and the negative terminal of the last battery will be the positive and negative terminals of the battery bank.
Batteries connected in series must have the same voltage and capacity ratings. Connect in parallel - Connecting two or more batteries together in parallel will increase the overall capacity. For example, if you connect two 12V 90Ah batteries in parallel, you will have a battery voltage of 12V and a capacity of 180Ah.
The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries, keeping the same capacity. Following this example where there are two 12V 200Ah batteries connected in series, we will have a total voltage of 24V (Volts) and an unchanged capacity of 200Ah (Ampere hour).
Connect in series - Connecting two or more batteries together in series will increase the overall voltage. For example, if you connect two 12V 75Ah batteries in series, you will have a battery voltage of 24V and a capacity of 75Ah. Batteries connected in series must have the same voltage and capacity ratings.
