Why are lithium batteries connected in series?
Lithium batteries are connected in series to increase the nominal voltage rating of one individual battery. This is done by connecting it in series strings with at least one more of the same type and specification to meet the nominal operating voltage of the system the batteries are being installed to support.
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.
How to connect lithium ion batteries in series?
To connect lithium-ion batteries in series, connect the positive connection of the first cell to the negative connection of the next one. This process is straightforward, but it's important to understand some key elements before doing so.
Can lithium batteries be charged in series?
Yes, lithium battery cells can be charged in series. This is a common practice used in various devices like ebikes, laptops, and other battery chargers. When charging lithium batteries in series, the charge voltage is divided among the number of cells in series.
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.
