What People Say
The welds hold perfectly with my spot welder. It’s much easier to work with than the thinner strips I used before.
Great quality nickel. It arrived quickly and the 27mm width was exactly what I needed for my 4P battery pack project.
Solid material that doesn't crack when bent. My battery pack build feels much more professional using this strip.
Problem & Solution
Building a custom lithium battery pack is a rewarding project, but the biggest hurdle for DIY enthusiasts is achieving a reliable, low-resistance connection between cells. Using subpar materials often leads to weak spot welds, overheating, or dangerous voltage drops that can ruin your expensive 18650 cells.
This 0.15x27mm nickel strip is specifically engineered to solve these connection issues. By providing the perfect balance of thickness and width, it ensures optimal current flow while remaining easy to manipulate during the spot welding process. It eliminates the frustration of brittle joints, giving you the peace of mind that your battery pack is safe, efficient, and built to last.
Who Is It For?
This product is designed for DIY electronics hobbyists, e-bike builders, and RC enthusiasts who are assembling their own lithium battery packs. It is the perfect tool for those looking to upgrade their battery storage capacity using 18650 cells.
It is also a must-have for repair technicians and makers who need a reliable, high-purity nickel solution for spot welding configurations ranging from 2P to 7P. If you prioritize safety and performance in your power projects, this strip is for you.
