A hybrid energy storage module includes a bus lead and two or more high-power modules connectable to the bus lead. A controller is operably connected to a first of the high-power modules and a second of the high-power module. The controller has a pulse mode, where the first high-power module is connected to the bus lead. The controller also has an extended mode, where both the first high-power module and the second high-power module are connected to the bus lead.
