A battery comprises a plurality of battery modules. A method determines a load-state of the battery and selects a set of the battery modules to configure, to produce a load-state capacity of the battery based on the load-state. A load-state capacity of the battery can be a sub-capacity of the battery less than a rated capacity of the battery and the method can configure the set of battery modules to produce the sub-capacity based on the load-state comprising the battery disconnected from a load. A battery system can comprise a battery having a plurality of battery modules and a controller configured to perform the method. A battery system can comprise a battery having a plurality of battery modules, and an actuator and a module retainer that can position a battery module in or out of contact with a module interconnect.
