Wow!!!
I feel so relieved that it was not quantum entanglement at work after all! Although after reading your link to the bi-directional BIRD thing, I think I understand quantum entanglement better than our Intellitec electronics.
On the Intellitec Battery Watch add-on to its USE/STORE house batt disconnect, if we do have one, and if they are common to all RVs, there are hundreds of RV.net posters who need to know this so they might save the money to upgrade and/or save the worries about battery cooking at CGs.
When I was trying to get answers on this stuff, I don't think very many posters seemed to be aware of what you are uncovering here.
Great quality of research effort. Snowman.
