A bus bar including a first end comprising a first material and a second end comprising a second material and a method of manufacture are provided. The first end is designed to be coupled to a terminal of a first battery cell of a battery module and includes a first collar disposed on the first end designed to receive and surround the terminal of the first battery cell of the battery module. The second end is designed to be coupled to a terminal of a second battery cell of the battery module and includes a second collar disposed on the second end designed to receive and surround the terminal of the second battery of the battery module. The first and second batteries of the battery module are adjacent to one another. Moreover, the bus bar includes a joint electrically and mechanically coupling the first end and the second end.
