What People Say
These strips welded perfectly with my spot welder on the first try, no issues at all.
Great value for the price. They are the perfect thickness for my 18650 power bank project.
Fast shipping and the quality is exactly as described. Will definitely buy more for my next build.
Problem & Solution
Building a custom battery pack is a rewarding project, but the frustration begins when you can't get a solid, low-resistance connection between your cells. Using improper materials or poor-quality strips often leads to overheating, weak welds, and potential safety hazards that could ruin your expensive lithium cells.
This 0.12mm nickel-plated strip is the perfect solution for DIY battery builders. Designed specifically for 18650 cells, it provides the ideal balance of conductivity and weldability. It takes the guesswork out of your build, ensuring that your spot welder creates a strong, permanent bond that keeps your battery pack running cool and efficient for years.
Who Is It For?
This product is designed for DIY electronics hobbyists, RC enthusiasts building custom power supplies, and solar energy storage tinkerers who need reliable components for 18650 battery pack construction. It is also ideal for repair technicians who need a cost-effective, high-quality solution for restoring damaged battery packs.

FAQ
Yes, they are suitable for most standard hobbyist applications, though for extremely high-drain projects, you may want to double-stack the strips.
Yes, these nickel-plated strips are compatible with almost all battery tab spot welders on the market.
This product is nickel-plated steel, which is the industry standard for cost-effective battery assembly.
For a standard 10s4p configuration, we recommend purchasing at least 3-4 packs to account for the necessary series and parallel connections.
Final Verdict
For the price of $1.85, this 30-piece nickel strip set is an absolute steal for any DIY battery builder. While it is nickel-plated rather than pure nickel, it performs exceptionally well for standard 18650 applications, providing consistent welds and reliable conductivity.
