Abstract: Methods and systems for selectively connecting a plurality of battery cells in a dual-mode battery pack in series and parallel configurations and/or for individual cell monitoring. A dual-mode battery pack may generally include a housing; a first set of battery cells connected in series; and a second set of battery cells connected in series. The battery pack may also include series connection contacts selectively connectable to the first set of battery cells and to the second set of battery cells and, when engaged, connecting the first set of battery cells and the second set of battery cells in a series configuration; and parallel connection contacts selectively connectable to the first set of battery cells and the second set of battery cells and, when engaged, connecting the first set of battery cells and the second set of battery cells in a parallel configuration.
