It is true that at 95% SOC at 13.6v you get more amps flowing by cranking the voltage up to 14.8v.
But if the batts are truly full at 13.6v, and you crank up the voltage so amps now flow, it does not make the batts will get any more full. Full is full by definition. It just heats them up. Not good for AGMs to dry them out doing that.
The question is whether you are truly full when amps stop flowing at 13.6v, and how can you tell? Hydrometer tells you with Wets. AGMs?
In summer, I had to change my solar to drop to Float early afternoon instead of staying at Vabs till dark, because the batts were losing water and the hydrometer said they were full by then.
I can imagine it would Be scary with AGMs to avoid that kind of thing, so I think Phil is right to be cautious with his AGMs.
Especially since he is successful in having them last for many years camping his way. He has nothing to gain by changing his procedures.
Doesn't mean his procedures will work for anyone else unless he is camping the same way as Phil.
