In an embodiment, a system may include at least one system component associated with a power load, a battery group, and control circuitry. The battery group may include multiple battery packs connected in a series connection. The control circuitry may: monitor a voltage level of each battery pack in the battery group during a discharge to the power load of the at least one system component; determine discharge capabilities for the battery packs in the battery group; and in response to a determination that the power load of the at least one system component exceeds a lowest discharge capability of the plurality of battery packs in the battery group, reduce the power load of the at least one system component below the lowest discharge capability of the plurality of battery packs in the battery group.
