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 (...

Bigger is not always better. It is possible to have too much charger, drastically shortening battery life. Two batteries each capable of absorbing 35 amps would be fine on a 55 amp charger. One such battery, however, would be in trouble.
My understanding is that battery will only absorb what it can and it will not be damaged. The converter will only supply what amps the battery will take. No harm done.
The waste is if the converter you bought for a bunch could supply 100 amps and the battery will only accept 40 amps when a 40 amper costs a bunch less than the 100 amper..
