Should you choose a series or parallel lithium battery installation?

As lithium batteries become increasingly popular, it is essential to understand the practical implications of different styles of installation. The choice between a series or parallel configuration depends on several factors, primarily dictated by the intended application.

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 do I charge a lithium battery?

This is due to the different number of cells. Use a battery charger suitable for lithium batteries, such as a Blue Smart charger. Set the charger to the charge profile as indicated in the above table. The supervisor connects with the VictronConnect app to the battery. The supervisor monitors the individual cell voltages at all times.

How do I connect multiple batteries in series?

Connecting multiple batteries in series Each individual battery needs to have been fully charged and balanced. Connect a maximum of four 12.8V batteries or a maximum of two 25.6V batteries in series. Connect the negative to the positive of the next battery. Fuse the series string on the positive side.

How do I choose a lithium ion battery?

Use lithium-ion batteries with the same capacity and voltage ratings. Identify the positive (+) and negative (-) terminals of each battery. Positive will typically be red and negative will be black Ensure proper alignment to prevent accidental short circuits. Calculate the total voltage needed for your application.

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.
