Premium Copper-Nickel Busbar for 21700 Battery Packs

High-purity copper-nickel alloy ensures superior conductivity and corrosion resistance, perfect for high-performance lithium-ion battery connections. Precision laser-cut tabs guarantee consistent thickness (0.2mm±0.02) for seamless spot welding.

8P parallel design optimizes current distribution across 21700 cells, reducing internal resistance by 15% compared to standard busbars. Electropolished surface prevents oxidation for long-term reliability in EV/powerwall applications.

CNC-formed edges eliminate burrs for safe handling. Compatible with automated battery assembly lines. Ideal for DIY power banks, solar storage systems, and e-mobility projects requiring stable 50A+ discharge.

Industry-leading 99.99% pure nickel plating enhances weldability. Ships in anti-static packaging with moisture barrier. Bulk discounts available for OEM/ODM orders.
