This disclosure details exemplary battery pack designs for use in electrified vehicles. An exemplary battery pack may include an enclosure assembly, one or more battery arrays housed within the enclosure assembly, a first battery internal component (e.g., an array holding device, heat exchanger plate, tray, etc.) adjacent to the battery array, a mounting bracket mounted to the first battery internal component, and a second battery internal component (e.g., a wiring harness of an electrical distribution system) elevated above the first battery internal component by the mounting bracket.
