UN 38.3
UN 38.3 is a safety testing standard that all lithium batteries must pass before they can be shipped or transported. Think of it as a safety passport for batteries. When you see this on a resume, it means the person has experience with making sure batteries are safe for transport by air, sea, or land. This is important because batteries can be dangerous if not properly tested and certified. The "UN" stands for United Nations, who created these rules, and "38.3" is simply the section number of these rules that deals specifically with batteries.
