A battery pack comprising a voltage bus 10, a first sub-pack 11 and a second sub-pack that comprises a plurality of modules 20, 21, 22. The battery pack is configurable into a first configuration in which the first sub-pack and the second sub-pack are connected in series across the voltage bus and the modules are connected in parallel within the second sub-pack. The battery pack is also configurable into a second configuration in which the first sub-pack and the second sub-pack are connected in series across the voltage bus and the modules are connected in series within the second sub-pack. The battery pack then switches between the first configuration and the second configuration when a voltage of the battery pack transits a first threshold. The battery pack may also comprise a third sub pack that is connected in series with the first and second sub packs in the first configuration and disconnected from the voltage bus in the second configuration.
