What is the difference between a Series and Parallel Connection? —The basics

 


There are 2 different ways of connecting batteries together to make a larger bank.

1. Parallel Connections – These connections are used when you want to increase the amperage of your battery bank. Most commonly, parallel-only connections are found in 12 volt systems. The connections on this type of battery bank go from positive to positive and negative to negative, when you connect this way you double your amps. (see the diagram below)

2. Series Connections – this type of connection is used when you need to increase the voltage of your battery bank. You will find these types of battery connections in all types of battery banks including 12 volt, 24 volt, 48 volt systems. The connections in this type of battery bank are different than parallel. Your batteries will be connected from positive to negative, linking the batteries together to increase the voltage of your battery bank. (see diagram below)

In some instances when you have a larger size battery bank you will commonly have both series and parallel connections in your battery bank.(see diagram below)
