A battery pack for powering equipment includes a core battery pack. The core battery pack includes a housing and a battery cell assembly positioned within the housing of the core battery pack. The battery cell assembly includes a first collector plate, a second collector plate, multiple battery cells, and multiple wire bonds. Each of the multiple battery cells has a first end and a second end. Each of the multiple wire bonds electrically connects the first end of one of the multiple battery cells to the first collector plate. None of the multiple wire bonds are coupled to a second end of one of the multiple battery cells.

Presented are metalworking systems for forming metallic workpieces, methods for making such workpieces and methods for operating such systems, and battery cell tabs bent by a multistage plunger press. A metalworking system includes a plunger fixture that mounts adjacent metallic workpieces, and a plunger head movably mounted to the plunger fixture to move between activated and deactivated positions. A first row of plunger fingers is mounted to the plunger head and moves in one direction to press against and bend one metallic workpiece a predefined bend angle. Likewise, a second row of plunger fingers is mounted to the plunger head and moves in an opposite direction to press against and bend another metallic workpiece another predefined bend angle. The plunger head then moves to the activated position, in tandem with the plunger fingers bending the metallic workpieces, to cause the plunger fingers to bend the workpieces additional respective bend angles.
