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 around 85% state of charge the most a 100 amp-hour battery can accept is about 12.5 amps. If voltage is increased, all that happens is gassing and heat.
