Something to note: DeWalt tool batteries don't have an internal BMS that can cut off the current on low charge, etc. They depend on the tool to do this! Really a bad idea to use them in another device that doesn't implement the BMS functions.
Also that video shows the guy putting 2 in series, which is a really bad idea if they aren't exactly the same health and SoC, as when the lowest gets low, it will attempt to reverse-charge it! You don't want a child's toy to burn your garage down!
