I've made an update to the code - Version 2.Here's a page on my website https://leonzak.com/batterychargermultiplexerversion2/ that has the details of the changes.
Wiring hasn't changed - I've changed the display, hopefully it conveys a bit more information.
The other change was to add a 3 second delay when the system switches between batteries being charged. The Harbor Freight charged seemed to get confused when switching without a delay. The 3 seconds fixes that. Any questions, please let me know.
