This disclosure details systems and methods for supporting and protecting vehicle underbody-mounted battery packs. An exemplary electrified vehicle may include a frame, a battery support structure mounted to the frame, and a battery pack. The battery pack is supported relative to the frame by the battery support structure but is not itself directly coupled to the frame. The battery support structure may be configured to provide an under-frame mounting configuration, cross member positioning, skid plate positioning for battery pack protection, weight optimized sub-components, unique shapes for ground clearances, etc.
