High-Precision Nickel-Plated Battery Connection Strips for Cylindrical Cells
Our nickel battery connection strips are specifically designed for cylindrical lithium battery pack assembly, including 18650, 21700, 26650, 32650, and 33140 cells. Available in multiple configurations such as single parallel, multi-parallel, offset, flat, bracketed, and W-type designs, these connector strips provide reliable electrical conductivity, consistent welding performance, and efficient battery pack production.
With a thickness of 0.15mm, the strips are widely used in energy storage systems, power tools, electric vehicles, e-bikes, backup power supplies, and custom lithium battery packs.
Key Features
Premium Nickel-Plated Material
Manufactured using an advanced penetration nickel-plating process, the nickel layer offers excellent adhesion and uniformity. This ensures:
Low internal resistance
Stable current transmission
Strong corrosion resistance
No peeling or oxidation during long-term use
High-Precision Wire EDM Manufacturing
All stamping dies are produced using Japanese Wire EDM technology, delivering:
Accurate dimensions
High consistency
Minimal assembly deviation
Smooth edges with low burrs
The precision design helps prevent damage to battery insulation film and improves overall pack safety.
Oil-Free Surface Treatment
Every nickel strip undergoes a degreasing process before shipment, resulting in:
Clean surface finish
Excellent spot welding performance
Easy soldering
Improved production efficiency
