Hi folks. In this video I show and explain how I built a custom battery & enclosure for my new kWeld DIY spot welder that I purchased from Keenlab. If you're interested, you can download the .stl files for 3d printing the custom enclosure and find the kWeld spot welder and 38120 battery cells at the links below.
