Two tool batteries connected in series

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.

How do I connect two batteries in a series?

Connect one end of a battery cable to the positive terminal (+) of one battery. Connect the other end of the cable to the negative terminal (-) of the second battery. Repeat this process until you have connected all batteries in a series, always connecting positive to negative and vice versa.

What is a series battery connection?

Series battery connection matches if you want to increase system voltage without having to alter the ampere-hours capacity (Ah). For example, connecting four 12V batteries in the series will generate a voltage of a total of 48V, which is often used in high-voltage power systems such as specific renewable energy systems.

How does a parallel battery connection work?

For example, two 12V 100Ah batteries connected to a series will produce 24V 100Ah. A parallel connection connects the terminal positive all batteries together, and also the battery negative terminal batteries connected together. This method would increase the capacity (Ah) of the entire battery used, while the voltage remained the same.
