For example, I came across this YouTube video in which the author tests a whole bunch of batteries and displays a series of bar charts showing each battery’s performance in various categories. How do content creators capture and log battery output like that? Is there a specific tool that plugs into a PC or records to a MicroSD card or something?
After some more digging, I believe “Computerized Battery Analyzer” is how they are called, based on this battery testing video by Lumencraft (at about 48 seconds in, he shows his testing setup). Thanks for chiming in!
