How much converter/charger is really needed?
I have a pair of NAPA 9824M Marine/RV batteries with a 20 hr rating of 79AH each, wired in parallel. Is there, really, any advantage in going from a 45 amp (PD4645V) converter/charger to a 55 amp (...

BFL13,
Bank bigger than the possible 20% charging rate is one of many reasons I went to dual banks. I can charge one while using the other. Use both, or charge both, depending on the source.
My OEM PD would not "do" 14.4 when the batteries were hungry. The Magnum does do that well, but I don't enjoy "dancing on the needles" any more.
Since I'm no longer full time, I'm back to low and slow maintenance charging on solar for most of the year.
In short, I no longer care much about treating the battery banks properly as the most they need to do is a couple of days use.
Low and slow with AGMs is what LY warns about that every so often you need to deep cycle them and do the high amps recharge. Same with Wets really.
Good to learn you will not have to sneak around this winter looking for an outdoor Xmas tree plug-in spot to run your shore cord over to. :)
