A battery pack comprising a voltage bus 10, a first sub-pack 11, a second sub-pack 12 and a third sub-pack 13. The battery pack is configurable into a first, second and third configuration. In the first configuration, the first sub-pack is connected to the voltage bus and the second sub-pack and the third sub-pack are disconnected from the voltage bus (11a). In the second configuration, the first sub-pack and the second sub-pack are connected to the voltage bus and the third sub-pack is disconnected from the voltage bus (11b). In the third configuration, the first, second and third sub-packs are connected to the voltage bus (11c). The battery pack switches between the first and second configuration when a voltage of the battery pack transits a first threshold, and switches between the second and third configuration when the voltage transits a second threshold.
