A battery module including bus bar cell interconnects and a method of manufacture are provided. The battery module may, in certain embodiments, include a housing, a plurality of battery cells disposed in the housing, and a bus bar cell interconnect. The bus bar cell interconnect is designed to electrically couple a first battery cell and a second battery cell. In some embodiments, the bus bar cell interconnect includes a first end electrically coupled with a first terminal of the first battery cell and a second end electrically coupled with a second terminal of the second battery cell. The bus bar cell interconnect also includes a curved portion disposed between the first end and the second end, and the bus bar cell interconnect is designed to distribute stress across the curved portion.
