You can see the battery serial number, cycle count and soh (state of health) if you open a log.bin file in a hex editor, in the first few lines of the file.
As well as the Show Anafi Log Project program I also use the free Notepad++ with Hex plugin (H circled in red), and I'm sure something similar would be available on a Mac.
