18650 & 21700 Nickel Plated Steel Battery Connection Strips for Spot Welding

High-Precision Nickel Plated Steel Connector Strips for Lithium Battery Pack Assembly

Our nickel plated steel battery connection strips are specially designed for 18650 and 21700 lithium battery pack assembly. Featuring an 18.5mm cell spacing and available in multiple parallel configurations, these pre-punched connector strips help improve production efficiency, ensure stable conductivity, and simplify battery pack welding processes.

Manufactured with precision stamping technology and premium nickel-plated steel material, these connector tabs are widely used in energy storage batteries, power tool batteries, e-bike battery packs, EV battery modules, and custom lithium battery systems.

Key Features

Premium Nickel-Plated Steel Material

The strips are produced using an advanced penetration nickel-plating process that provides:

• Uniform nickel coating thickness

• Strong coating adhesion

• Low electrical resistance

• Excellent conductivity

• Superior corrosion and oxidation resistance

• No peeling during welding and long-term use

High-Precision Wire EDM Tooling

All stamping dies are manufactured using Japanese Wire EDM technology, ensuring:

• Accurate dimensions

• Consistent hole spacing

• Minimal assembly deviation

• Smooth edges with low burrs

• Enhanced battery safety

The precision edge treatment helps prevent damage to battery insulation sleeves during assembly.

Degreased Surface Treatment

Every nickel strip undergoes professional oil-removal processing before shipment.

Benefits include:

• Clean surface finish

• Excellent spot welding performance

• Easy soldering

• Reduced welding defects

• Improved production efficiency

Available Thickness Options

• 0.12mm

• 0.15mm

• 0.20mm

Custom thicknesses and dimensions are available upon request.
