Battery packs get their desired operating voltage by connecting several cells in series. If higher capacity and current handling are required, the cells are connected in parallel. Some packs have a combination of serial and parallel connections. A laptop battery may have four 3.6-V Lilon cells connected in series to achieve 14.4 V and two cells in parallel to increase the capacity from 2000 to 4000 mAh. Such a configuration is called 4S2P, meaning four cells in series and two in parallel.
