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.
