This is a DIY Spot Welding kit that may be used to weld 18650/26650/32650 and other lithium batteries. For the power source, you'll need your own 12V battery. The standard 0.1mm-0.15mm nickel-plated sheet is simple to weld. To perform proper welding, the battery must have a current greater than 100A.
