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 (...

At what voltage sir? Starting with maximum absorbsion voltage of 14.8 and continuing?
Based on the charger at 14.6 and holding with no drop till batteries charged right up. However, the amps taper at a lower battery voltage than the 14.6 due to voltage drop while still at higher amps.
You only get the 14.6 at the batteries when amps have tapered right down.
