Claim 19:
20. A method for making a shear wall for a vehicle battery system having an assembly comprising a plurality of battery cells arranged in at least one enclosure, the method comprising:
forming a first element configured to be arranged along a lateral side of the assembly, wherein the first element comprises a first flange extending away from the side of the assembly;
forming a second element configured to be arranged above the first element along the lateral side of the assembly, wherein:
the second element comprises a second flange and a C-shaped lifting feature comprising a central portion that extends vertically away from an interface between the first flange and the second flange and two end portions that extend laterally away from the central portion, and
the first flange and the second flange are layered together to form the interface; and

welding the first element and the second element together to form a multi-layer mounting flange, wherein:
a weld path joining the first element and the second element is along a backside of the interface and proximal to an interior surface of the shear wall configured to interface with the assembly,
a weld seam along the weld path faces the lateral side of the assembly and does not extend out into a portion of the interface that extends away from the lateral side of the assembly, and
the first and second flanges extend laterally away from the weld seam.
