Abstract

An apparatus is provided that includes a two or more cell elements stacked internally to create a single cell with a non-uniform height. A first bus bar may electrically couple to a first side or first end of the cell elements in order to connect the terminals of the battery elements. A second bus bar may electrically couple to a second side or second end of the cell elements in order to connect the terminals of the battery elements.

Claims
