18650 Nickel Sheet 21700 Nickel Strip 26650 32650 Nickel Sheet Battery Connector Single And Multiple Parallel Staggered Nickel Sheet

1. Product Overview​​

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.
