How do you connect a battery in series?

When connecting batteries in series, the general advice is to use batteries of the same ratings and the same make and model in order to minimize differences in exact voltage and amperage. Note, we say ‘minimize’, because even batteries coming off the same production line can vary slightly in these measurements. Another factor is battery age.

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 charge a battery in series?

When connecting or charging batteries in series your goal is to increase the output of your batteries nominal voltage rating. To do this you need to connect the POS (+) terminal of the first battery to the NEG (-) terminal of the second battery.

How do I make a series-parallel battery bank?

If you have two sets of batteries connected in series, you can wire both sets into a parallel connection to make a series-parallel battery bank. In the images below we will walk you through the steps to create a 24 volts 70 AH battery pack.

Should you wire a battery in series?

When you need more voltage than a single battery can provide, wiring batteries in series is a popular and effective solution. By connecting multiple batteries in series, you can increase the total voltage while maintaining the same current capacity.

What is a series / parallel battery configuration?

The goal of the series / parallel configuration is to increase BOTH the voltage and capacity. Batteries that are ONLY in parallel keep the same voltage and increase their capacity. Batteries that are ONLY in series keep the same capacity and increase their voltage.
