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.
Overall capacity is added because power is measured in watts- and watts is volts multiplied by amp hours. Putting lithium batteries in series increases the overall voltage, which increases overall power. In this article, we will explain why you would want to wire lithium-ion batteries in series.
Wiring batteries in parallel is an extremely easy way to double, triple, or otherwise increase the capacity of a lithium battery. When wiring lithium batteries in parallel, the capacity (amp hours) and the current carrying capability (amps) are added, while the voltage remains the same.
Adding battery cells in series adds their voltages together while not changing the amp hours. It's important to consider, however, that because power is a measure of volts multiplied by amp hours, putting lithium batteries in series increases the overall power by increasing the overall voltage.
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.
Charging lithium battery cells while they are in a series configuration is not only possible but very common. It's how ebike, laptops, and just about any other battery chargers work. When charging lithium batteries in series, the charge voltage is divided among the number of cells in series.
