Key Features

High Current Density

Optimized cross-section design delivers maximum current capacity with minimum weight and volume.

Thermal Management

Laminated construction provides excellent heat dissipation, preventing hotspots in battery systems.

Weight Optimization

Precisely engineered to minimize weight while meeting current and thermal requirements - critical for EV range.

Vibration Resistance

Flexible design withstands automotive vibration and shock without fatigue or loosening.

Compact Design

Low-profile construction fits in tight battery pack spaces where rigid busbars cannot.

Safety Features

Insulation options meet automotive safety standards for high-voltage isolation.

Battery Pack Applications

Prismatic Cell Packs

Flexible connections between prismatic cells in module configurations.

Pouch Cell Packs

Low-profile busbars for connecting pouch cell tabs in series and parallel.

Cylindrical Cell Packs

Interconnects for 18650, 2170, and 4680 cylindrical cell modules.

Module-to-Module

High-current connections between battery modules within the pack.
