The present disclosure relates to battery system having a plurality of battery modules (206) and a battery management system (208). The plurality of battery modules (206) are arranged in series to define a battery string. Each of the plurality of battery modules (206) comprises a supervisory circuit (228), one or more cell packs (224), and one or more switches (238) to electrically connect the one or more cell packs (224) to the battery string (204). The battery management system (208) to selectively switch, for each of the plurality of battery modules, the one or more switches (238) between a first position that electrically places the one or more cell packs (224) in series with the battery string and a second position that electrically bypasses the one or more cell packs (224) from the battery string. The battery management system (208) is configured to electrically couple the battery string with a battery bus via a string switch.
