Abstract: A connector assembly for electrically connecting poles of two adjacent battery cell. The connector assembly comprises an electrically conductive bus bar having a first connection area and a second connection area distal from each other, electrically conductive pole-mating components having a pole-mating face and a bar-mating face, and fastening components for attaching the electrically conductive bus bar and one of the pole-mating components to one of the poles of the two adjacent battery cells. The pole-mating faces of the pole-mating components are adapted for mating the poles the battery cells. The bar-mating faces of the pole-mating components are adapted for mating with the connection areas. The bar-mating faces and the connection areas have complementary concave/convex arched shape for optimizing contact surface over a range of relative positioning of the two adjacent battery cells.
