A reconfigurable battery system is disclosed. The reconfigurable battery system comprises a reconfigurable battery cell array, a controller, and a bus switch. The battery cell array is configured to operate in a first discharge mode, a second discharge mode, or a charge mode. The battery cell array includes a plurality of battery cells arranged as at least a first column of battery cells between a second battery terminal and a first battery terminal and a switch between each battery cell within the first column of battery cells. The bus switch is in signal communication with the battery cell array at the first battery terminal and is configured to select between electrically connecting the first battery terminal to a normal voltage bus or a high-voltage bus.
