Pure nickel strip 0.15x8mm – low-resistance connections for 18650 and 21700 battery packs
Building a battery pack and don’t want to compromise on quality? This 99.96% pure nickel strip, measuring 0.15 × 8 mm and supplied in a 10-metre roll, is the professional choice for battery builders—from DIY projects to e-bike batteries and UPS systems.
Note: This product is sold exclusively as a 10-metre roll. It is not available by the metre or as individual pieces.
Why choose this nickel strip? (Key advantages):
- Pure nickel, not nickel-plated steel — 99.96% purity ensures lower electrical contact resistance, reduced heat generation, and cleaner welds compared to cheaper steel-based alternatives
- 8 mm width — perfectly sized to accommodate 2–3 spot welds per cell, ensuring even current distribution across the battery terminal
- 0.15 mm thickness for excellent weldability — compatible with small to medium-power spot welders, including popular hobbyist models; designed to weld securely without damaging the cell
- 10-metre roll — provides ample material for medium to large battery packs, including dozens of 18650 or 21700 cells, so you won’t run out mid-project
- Resistant to vibration and shock — essential for mobile applications such as e-bikes, electric scooters, and portable power tools where the pack is subject to constant mechanical stress
Performance and Specifications
Unlike nickel-plated steel strips, this product is manufactured entirely from 99.96% pure nickel—no steel core, no conductivity compromises. This ensures that internal connection resistance remains minimal even under high discharge currents, which is critical for demanding applications like e-bikes or power tools. The 0.15 mm thickness offers the perfect balance: robust enough for mechanical durability, yet thin enough for precise welding without compromising the cell terminal. Compatible with 18650, 21700, 26650, and all standard cylindrical cells.

Frequently Asked Questions
Is this pure nickel or nickel-plated steel?
It is 99.96% pure nickel—no steel core. This provides superior conductivity, cleaner welds, and eliminates the risk of accelerated oxidation at the connection point.
Does it work with hobbyist spot welders?
Yes. The 0.15 mm thickness is specifically designed for small and medium-power spot welders, including the popular models used in DIY battery building.
How many 18650 cells can I cover with a 10-metre roll?
This depends on your specific configuration and the number of weld points per cell. As a guide, 10 metres is sufficient for medium to large-scale packs with dozens of 18650 cells connected in series/parallel.
Can I buy it by the metre instead of a full roll?
No. This product is sold exclusively as a 10-metre roll. We do not offer it by the metre or in smaller quantities.
