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 (...

If you have a 1000w generator that runs the 45 amper, that gen will not be able to run the 55 amper. If you have a 2000w gen you are ok going to the 55.
On 158 AH starting at 50% SOC, there will be only a few minutes difference in charging time to 80%.
If you decide to get a higher AH battery bank such as a pair of 6s, now the 55 amper would be better (although a 75 amper would be just right.)
If you don't do much generator charging but are on shore power or solar mostly, then IMO not worth changing to a 55.
