What People Say
The strip welds perfectly with my DIY spot welder on the first try.
Great quality for the price. Used it to rebuild my cordless drill battery and it works like new.
Fast shipping and the material is exactly as described. Perfect for my 18650 projects.
Problem & Solution
Building your own battery pack for e-bikes, power tools, or portable projects is incredibly rewarding, but the biggest hurdle is creating a reliable, low-resistance connection between cells. Using sub-par materials leads to overheating, voltage drops, and, in the worst cases, dangerous connection failures that can ruin your expensive battery cells.
This 18650 nickel-plated steel strip solves the connectivity nightmare by providing a consistent, easy-to-weld bridge for your cells. It is engineered to handle the high current flow required for high-drain applications, ensuring your pack stays cool and efficient. Whether you are a hobbyist or a professional tinkerer, this strip gives you the peace of mind that your battery pack is built to last.
Who Is It For?
This product is designed for DIY electronics enthusiasts, e-bike builders, and RC hobbyists who are assembling custom lithium-ion battery packs. It is also a staple for repair technicians who need to replace damaged battery connectors in power tools or portable devices.

Pros & Cons
Pros
- Extremely affordable entry point for battery builders
- Easy to cut and shape for complex pack configurations

FAQ
This is a nickel-plated steel strip, which is the industry standard for 18650 spot welding due to its excellent balance of conductivity and weldability.
While you can solder it, we highly recommend spot welding to avoid heat-damaging the lithium-ion cells.
If you are just doing a small repair, the 1m strip is fine. For custom e-bike or power wall projects, the 10m roll is much more cost-effective.
Final Verdict
For the price of $1.38, this nickel-plated steel strip is an absolute 'must-have' in any electronics workbench. It performs exactly as expected, offering reliable, low-resistance connections that make spot welding a breeze. If you are serious about building safe, long-lasting battery packs, this is the most cost-effective investment you can make.
