Review on High Purity Nickel Strip 2P for 18650 Battery Spot Welding (0.15x27mm 2M) by Neal Martin

Pure nickel strip worked well on my e-bike battery. The spot welds were strong. Measured directly at a thickness of 1.5 mm. I've tested to make sure it's pure nickel: Salt bath grinding spark test No corrosion, no sparks confirm it's pure nickel. Some reviewers mention magnetic properties. Nickel is attracted to magnets, so it's not the best test to compare it to plated steel strip. The grid pattern matches the battery holders I use.
