Abstract: A power pack assembly (10) for operating equipment such as video equipment (12) including a plurality of power cells (14). The power cells (14) are connected in series to operate video equipment (12). A housing supports the power cells (14) and includes nonconductive partitioning walls (36) within the housing (35) for insulating and separating the adjacent ones of the power cells (14) from each other. A method is provided for making the power cell assembly (10) including the steps of disposing the plurality of power cells (14) between the partitioning walls (36) of the base member (42) and adjacent the floor portion (44) thereof, electrically connecting the power cells (14) in series within the base member (42) and enclosing the connected power cells (14) to provide external insulation between the connected power cells (14) and the external environment.
