Phil, you charge at the Float voltage so of course you don't see the overcharge thing.
BF, I base what I said on - after the AGMs have been fully charged on whatever charger - I start up the cold V10 engine such that it's alternator jumps to, and holds, around 14.4 volts for awhile. The RV batteries' ammeter doesn't budge ... it just sits there still showing near zero amps acceptance by the batteries. Recall that this is with a 130 amp alternator that is capable of delivering around 70 amps at engine idle speeds. (The alternator is over-driven, so it spins at far greater RPM than what the big engine is idling at.)
That's what I mean when I say that my AGMs seem to hit a solid wall preventing the acceptance of any more current once they're full up.
