Tool lithium battery series connection

What is the goal of connecting lithium batteries in series?

Lithium batteries are connected in series when the goal is to increase the nominal voltage rating of one individual lithium battery.

What should you connect first when wiring lithium batteries in series?

To connect lithium-ion batteries in series, all you have to do is connect the positive connection of the first cell to the negative connection of the next one. Connecting battery cells in series is a pretty straightforward process, but there are some key elements that should be understood before doing so.

Are lithium-ion batteries wired in series?

In fact, every battery pack we sell consists of a collection of cells that have been wired in series (and often in parallel, too). In this guide, we'll walk you through the steps of safely wiring lithium-ion batteries in series to create a higher voltage battery pack for your projects.

When should a lithium battery be connected in series?

You should connect lithium batteries in series when your device requires a higher voltage than a single battery can provide. For example, if your device operates at 7.4V, connecting two 3.7V batteries in series would be appropriate. This setup is commonly used in applications like electric scooters, drones, or other high-voltage devices.

What is a series battery connection?

A series connection involves linking batteries end-to-end to increase the total voltage while keeping the same capacity (measured in milliampere-hours, or mAh). For example, connecting two 3.7V 100mAh lithium cells in series will yield a total voltage of 7.4V, but the capacity remains 100mAh.

What happens if you connect two lithium batteries in series?

When you connect two 12.8V-100AH lithium batteries in series, they become a 25.6V-100AH battery bank with 2560 watts of stored energy potential to 100% DOD. Connecting batteries in series increases the battery bank voltage and total stored energy.
