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.
Connecting battery cells in series is a pretty straightforward process, but there are some key elements that should be understood before doing so. 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.
Use a heat gun to shrink the tubing, providing insulation and additional structural support. Use a multimeter to measure the overall voltage of the series-connected batteries. Place the wired batteries in a secure battery holder or pack. Ensure the pack is well-insulated and won't be subjected to physical stress.
