21700 18650 Nickel Strip Sheet 0.12-0.2mm Thickness for Battery Connector Single Multiple Parallel Staggered Layouts
Our high-precision battery nickel strips are engineered for secure and efficient welding of lithium battery packs including 18650, 21700, 26650, and 32650 cells. Available in single and multi-cell configurations with adjustable pitch spacing, these strips ensure low resistance, high conductivity, and mechanical durability for solar, EV, and energy storage applications.
Supports 18650 (18.5mm/19mm pitch), 21700 (21.5-23mm pitch), 26650, and 32650 cells
Available in 0.12mm, 0.15mm, and 0.2mm thickness options to balance flexibility and current capacity
Choose from horizontal, vertical, cross grooves, screw holes, or no grooves to match your specific requirements
Laser-cut square holes (11.5-15mm) with 7-8mm shoulders for perfect battery cell alignment
