Abstract: A battery cell assembly includes a battery cell and a battery cell holder. The battery cell has a cell casing. The cell casing has an outer casing surface. The outer casing surface has a first plurality of grooves formed therein. The battery cell holder has a plurality of cell pockets. Each of the cell pockets has a wall. The wall has a wall surface. The wall surface has a second plurality of grooves that interact with the first plurality of grooves on the outer surface of the cell casing. The interaction of the first plurality of grooves on the cell casing with the second plurality of grooves on the wall of each of the plurality of cell pockets cooperates to prevent the battery cell from moving relative to the battery cell holder.
