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.
So if you were to connect a 12v 50Ah battery in series with a 12v 100Ah battery, the result would be a 24v 50Ah battery. DO NOT CONNECT BATTERIES OF DIFFERENT CAPACITIES IN SERIES. Working with lithium-ion batteries requires careful attention to safety.
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.
In the lithium battery pack, multiple lithium batteries are connected in series to obtain the required operating voltage. If what is needed is higher capacity and higher current, then lithium batteries should be connected in parallel.
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.
So, in review, wiring lithium batteries in series is just as simple as wiring lithium cells in series. The difference is that lithium batteries have a BMS which contains MOSFETs that might not be able to handle the higher voltage that they would experience when one battery dies.

What are the implications of connecting lithium battery packs in series?
$begingroup$ You can always connect two battery packs in series. The problem is to keep the stronger cells from reverse-biasing the weaker and destroying them. In your case, the thing to do is provide a simple voltage-sensing circuit for each battery pack, and if either pack gets a voltage too low, you MUST turn off power to the load.
