99.96% Nickel-Plated Steel Strip 0.15x8mm – Reliable Connections for 18650 and 21700 Battery Packs
Building a custom battery pack and don’t want to risk it all with cheap, substandard strip? This nickel-plated steel strip (99.96% coating) measuring 0.15 × 8 mm on a handy 10-metre roll is a go-to choice for DIY projects, e-bike builds, and UPS power 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 benefits):
- 99.96% Nickel-coated steel — provides solid electrical conductivity, clean welds, and reliable corrosion protection compared to budget alternatives
- 8 mm width — easily accommodates 2–3 spot welds per cell, distributing current evenly across the battery terminal
- 0.15 mm thickness, excellent weldability — compatible with hobbyist and standard low-to-medium power spot welders without burning through the cell
- 10-metre roll — plenty of length for medium-to-large battery builds featuring dozens of 18650 or 21700 cells, so you won’t run out mid-project
- Resistant to vibration and repeated shocks — essential for mobile applications like e-bikes, electric scooters, and cordless power tools subject to constant mechanical stress
Details and Performance
Unlike bare steel alternatives, this strip features a 99.96% nickel coating over a steel core, striking the ideal balance between mechanical tensile strength and electrical performance. The nickel plating ensures low contact resistance and clean spot welds for demanding applications such as e-bike batteries and power tools. The 0.15 mm gauge offers the sweet spot: sturdy enough to handle high currents, yet thin enough for precise spot welding without damaging cell terminals. Fully compatible with 18650, 21700, 26650, and any standard cylindrical cell.

Frequently Asked Questions
Is this pure nickel or nickel-plated steel?
It is 99.96% nickel-coated steel. The plating delivers reliable electrical conductivity, clean welds, and effective corrosion resistance at the joints.
Will this work with hobbyist spot welders?
Yes. The 0.15 mm thickness is specifically engineered for low and medium-power spot welders, including popular DIY battery building kits.
How many 18650 cells does a 10-metre roll cover?
It depends on your pack configuration and how many welds you use per cell. As a general guide, 10 metres is enough for medium to large battery packs containing dozens of series-parallel 18650 cells.
Can I buy this by the metre instead of a full roll?
No. This product is sold exclusively as a 10-metre roll. Individual metres or smaller quantities are not available.
