Zusammenfassung:	A multi-cell battery powered device can include at least one power input, a first power converter coupled between the power input and a battery bus, a second power converter coupled between the battery bus and a system load of the electronic device, a plurality of cells, and a plurality of primary battery protection switches. The primary battery protection switches can be selectively operable to couple the plurality of cells in: (1) a parallel configuration in which the cells are coupled to the battery bus so as to charge or discharge in parallel, (2) a series configuration in which the cells are coupled to the battery bus so as to charge or discharge in series, and (3) an isolated configuration in which at least one of the plurality of cells is coupled to the battery bus and at least one of the plurality of cells is disconnected from the battery bus.
