Battery cell connector

A battery cell connector comprising:

• a first limb having a length extending in a first direction, a width extending in a second direction, and a height extending in a third direction, the first limb having a top and a bottom, each defined by the length and width and a first side and a second side, each defined by the length and height;
• a second limb having a second limb width extending in the first direction, a second limb length extending in the second direction and a second limb height extending in the third direction, the second limb length extending in the second direction away from the first side of the first limb;
• a first shoulder connecting the first limb and the second limb, the first shoulder extending along the length of the first side of the first limb in the first direction, the shoulder having a height extending in the third direction;
• a second shoulder comprising a beveled region and a wall, the beveled region extending from the first shoulder to the second side of the first limb in the second direction, the beveled region coupled to the first shoulder and the first limb, the wall connecting the beveled region to the first limb;
• wherein the first direction, second direction, and third direction differ from each other;
• and
• wherein the first shoulder increases in thickness as measured in the second direction from a first end of the first shoulder to a second end of the first shoulder, the first end comprising an intersection of the first limb, second limb, first shoulder, and second shoulder, and the second end comprising an intersection of the first shoulder with the first limb the second end being spaced apart from the first end as measured in the first direction;
• and
• wherein the first shoulder decreases in height as measured in the third direction in a convex and nonlinear manner from the first end to the second end.
