A battery system for an electric vehicle includes a fixed cover, and a removable cover arranged over battery modules and a high voltage distribution system. The battery system includes a busbar arranged at least partially over a region of the battery modules and under the removable cover. The busbar includes a fixed section and a movable section, or a hinge, such that the busbar can be repositioned out of the way. The support tray includes a link between the fixed and movable sections. Floating fasteners, allowing at least one of radial float and axial float are used to secure the link to the support tray, thereby avoiding safety hazards and reducing the potential for short circuits in high voltage distribution systems or conductors thereof. The floating fasteners include a head, a neck, an engagement section, and a washer, which prevent removal from a component once installed.
