Copper Bus Bar 82x20x2mm

COPPER BUS BAR 82x20x2MM

The COPPER BUS BAR 82x20x2MM is a copper battery busbar designed for rigid electrical interconnection in prismatic lithium battery packs. Copper provides high electrical conductivity and is widely used for compact, low-loss battery interconnections. The 82 x 20 x 2 mm format gives the part a defined geometry for battery-module assembly. The product is suitable for EV, ESS, inverter, solar-storage and industrial battery-pack assembly.

A battery busbar replaces long flexible cable runs between adjacent cell terminals with a short, rigid conductor. This helps battery builders create a compact series or parallel current path while keeping the module layout neat and serviceable. The COPPER BUS BAR 82x20x2MM is positioned as a lithium battery busbar / prismatic cell interconnect, with its 82 x 20 x 2 mm and flat battery busbar / cell interconnect making it easy to identify for production, replacement and custom pack-building requirements.

Copper provides high electrical conductivity and is widely used for compact, low-loss battery interconnections. In prismatic battery modules, a properly designed busbar also simplifies pack assembly because the electrical path, terminal spacing and mechanical fastening are handled in a compact component rather than separate cables and lugs.

The busbar's electrical role is to transfer charge and discharge current between battery connection points with minimal unnecessary conductor length. Copper is a proven busbar material for lithium battery systems, and the rigid profile helps maintain a stable cell-to-cell connection inside the module. The 82 x 20 x 2 mm format gives the part a defined geometry for battery-module assembly.

For flat busbar variants, the stated width and thickness create a broad conductor section that also provides useful mechanical stiffness. A 3 mm profile offers greater conductor section and rigidity than a 2 mm profile of the same width, while compact 2 mm links are common where lower weight and tighter packaging are priorities. Stud and clinch variants streamline fastening by integrating the terminal hardware into the interconnect format.

The COPPER BUS BAR 82x20x2MM is suited to prismatic LiFePO4 and lithium-ion battery modules that use a busbar in this 82 x 20 x 2 mm / connection format. It can be used in series or parallel cell groups, battery-module prototypes, replacement work and production assemblies. The rigid terminal-to-terminal interconnect makes the part especially practical for pack builders who want a compact, rigid connection instead of a flexible jumper between adjacent terminals.

Applications

• Prismatic LiFePO4 and lithium-ion battery packs for direct cell-to-cell electrical interconnection.

• EV, e-rickshaw and light-electric-mobility battery modules.

• Solar, inverter and stationary energy-storage battery systems.

• UPS and backup-power lithium battery assemblies.

• Battery pack manufacturing, prototyping, repair and module rebuild projects.

Installation Guide

Position the component squarely on clean battery terminals or enclosure hardware and keep polarity clearly identified throughout assembly. Use the battery-cell or enclosure manufacturer's specified fastener stack and tightening torque so the connection remains mechanically stable without stressing the terminal. Keep conductive tools insulated around energized cells and prevent loose hardware from falling across adjacent terminals.

After assembly, inspect the connection for full seating, alignment and secure fastening. For busbars and terminals, a clean contact surface and firm mechanical joint support efficient current transfer. For enclosure fasteners, ensure the mounted hardware sits flush and does not interfere with insulation, wiring or nearby cells. A final visual inspection and controlled pack test help maintain consistent production quality.

For volume production, standardize the busbar or fastener part number in the battery BOM so the same geometry and hardware are used across every pack. This improves repeatability during assembly, service and future replacement work.
