Rigid Insulated Battery Busbar for 280Ah/320Ah ESS Cells

This rigid insulated battery busbar uses a single solid flat metal conductor rather than stacked copper foils, giving it a fixed formed geometry instead of the compliance associated with flexible laminated busbars. The conductor is bent into offset shapes, covered through the central section with orange insulation, and left exposed at the terminal areas for bolted electrical connection. This construction closely matches the rigid insulated busbar configuration used on your website.

The busbar is intended for fixed interconnection of 280Ah/320Ah large-format energy storage cells and related battery module assemblies. Its terminal holes allow mechanical fastening to cell connection points, while the insulated central section helps separate conductive surfaces within the pack. For custom busbar manufacturing, the bend geometry, terminal layout and connection arrangement can be adapted to OEM battery pack layouts and installation space.

Design & Application

The busbar features a solid, multi-layered copper construction with a pre-formed bend, distinguishing it from flexible, foil-based alternatives. The orange insulation sleeve provides protection against short circuits, while the punched holes at each end are designed for secure screw-fastening to battery terminals. This rigid design ensures stable, low-resistance connections essential for the high-current demands of 280Ah/320Ah battery systems.
