Supports 3.65V lithium iron phosphate, does not support disposable dry batteries, nickel mextal hydride, nickel chromium, lead-acid batteries, etc. The battery has a minimum of 2 strings and a maximum of 6 strings, and the total voltage cannot exceed 23V. The single string battery needs to be able to charge and discharge currents of at least 10A. If it cannot be reached, please lower the power.

You will not be connecting them in series. You are correct, 3s, 4s, and 5S is for the number of cells. If you order the wrong one you will need to rearrange jumper settings, so best to get the version
                                                                                                                    for the number of cells you wish to use. Protection is not provides under all circumstances, so be sure to print out the info and read it carefully. Very sophisticated, but the makes it more complicated to configure and use. I would rate it as a medium complexity project, not a beginner project.
