I posted that I did not wish to be rude... Your reply borders on that !As low as 12.7V? battery recovers to 12.8V when the heating is off? I would be inclined to check your voltmeter against another one!
As far as OTT for most of us, maybe, but more and more people are looking at going Electric (just look at the 'Electric Car' topic!) and to get the optimum use for a Battery Bank, you have to know what is available.
This is posted in the Forums '... Technical Section' also.
Simple answer ... Not Interested, Don't Read? (I take that approach in the "Jokes" section as I am a boring old fart)
I have read you other posts with interest....( and this one ) it is a shame you do not appreciate other opinions !
I did not contradict anything you posted I just offered my take on it
I have used this system to monitor my LB for the lats 3 years without problem
Ok I have not posted detailed voltages/monitoring etc but IT WORKS !.
Why do you suggest the reading is inaccurate when you have NO knowledge of my setup.
