A battery pack comprising a voltage bus 10, a first sub-pack 11 and a second sub-pack 12. The second sub-pack comprises a plurality of modules 20, 21. The battery pack is configurable into a first configuration in which the first sub-pack and the second sub-pack are connected in parallel across the voltage bus and the modules are connected in parallel within the second sub-pack (7a), 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 parallel within the second sub-pack (7b) 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 be configurable into a third configuration where the first sub pack and second sub pack are in series, and the modules in the second sub pack are also in series.
