Sort of, the letter S really really refers to the cells in [S]eries. Each Lipo cell is nominally 3.7 volts. With battery cells if you connect the negative of one cell to the positive of a second cell this is what is meant by connecting in series and the voltage will double if you measure from the positive of the first cell to the negative of the second cell you will see 7.4 volts. This is a 2S battery, 3S are three cells in series giving 11.1 volts, 4S = 14.8v and so on.
You can connect batteries in parallel as well giving the same voltage but doubling the capacity so you could have a 2S2P (P for parallel) battery giving 7.4 volts and double the capacity using 4 cells, 2 parallel pairs in series.
