RE: Trouble with my battery bank
For no reason of evidence I am suspicious of the Nanopulser.* I have them as well, but the only reason a battery fails early outside of a manufacturing defect or bad maintenance and operation, which seems unlikely or already ruled out, is over-charging or chronic under-charging.* Under-charging would affect all batteries. Over-charging should affect all batteries as well, especially given the clean cables.* That leaves the possibility that this is all just a sad cry for attention, or some other anomaly.* The Nano by the process of elimination seems to be what is left.*
Perhaps check voltage under all conditions, alternator charging, shore power charging, resting with and without the Nanopulser, each battery positive to ground under all conditions.* There must be a voltage differential developing somehow that is draining the front battery into the others, slowly killing it.
That, or you made it all up.
