Review on 🔋 Portable Mini Battery Spot Welding Machine Set for 18650 Lithium Battery, Household Spot Welder with Nickel Belt & Rechargeable Power Tools by Brad Davis

I'm not a professional battery fitter or anything but this thing works really well for my purposes. After fully charged, it did not lose bulbs due to charging after making 3 batteries (about 50 welds). The welds are pretty strong depending on the placement of the bars. But overall I bought it for $25 on sale but it's as good as any other cheap spot welder so I'm more than happy with it, especially after buying another model that was faulty.
