David, I wasn’t aware of the ability to choose which supply (internal Vs. external) was being reported! Thanks for bringing that to my attention. I’ll bet you’re exactly right - that the internal battery voltage rises a bit when external power is supplied. I’ll check this out as soon as I get home this evening.
