fyi, the 1s indicates the number of cells in series. there are some battery packs that have a configuration defined as XsYp, X cells in series and Y cells in parallel.
the # of cells in series sets the voltage and need to be balanced while the cells in parallel set capacity and are balanced automatically (2 cells in parallel see the same voltage during charge and discharge)
