Our high-precision battery nickel strips are engineered for secure and efficient welding of lithium battery packs (18650, 21700, 26650, 32650). Available in single/multi-cell configurations with adjustable pitch spacing, these strips ensure low resistance, high conductivity, and mechanical durability for solar, EV, and energy storage applications.

2. Key Features

Universal Compatibility: Supports 18650 (18.5mm/19mm pitch), 21700 (21.5–23mm pitch), 26650, 32650 cells.
Optimized Conductivity: 0.12/0.15/0.2mm thickness options balance flexibility and current capacity.
Customizable Designs: Choose horizontal/vertical/cross grooves, screw holes, or no grooves.
Precision Engineering: Laser-cut square holes (11.5–15mm) + 7–8mm shoulders for perfect alignment.
Adjustable Spacing: Roll-direction spacing can be tailored to battery pack layouts.
