1. A ballistic resistant case for a secondary battery comprising:
a rectangular metal case having: a front wall and two side walls and a rear wall extending up from a bottom wall; a panel connected to said bottom wall and the side walls to divide the internal space of the case into cell pack receiving bays; and a cover to seal the cell pack receiving bays;
a bus bar contacting the front wall and extending from the front wall, across the top of the panel, to contact the rear wall; and
a connector extending through the bus bar to secure the cover to the panel with the bus bar sandwiched therebetween, wherein the bus bar is electrically insulated from the connector and the cover and the panel, whereby the bus bar reinforces a central portion of the cover and prevents the panel and the walls from deflecting to provide ballistic protection for the cell pack receiving bays.
