Onboard converter amps output for battery charging

Just curious as I'm out dry camping this weekend and am able to run a generator during the day and running off batteries all night. I have a typical WFCO converter and the manual states "fast recharge rate depending on battery condition and load".
Just wondering what kind of charging rate they're talking about and how long it would take to fully charge a couple of agm 12v trolling motor batteries.
I know the converter itself probably puts out 55 amps or so but how many of them are actually used for onboard battery charging?

    Do you have a way to monitor voltage during the recharge? If the converter is putting out 14.3 to 14.5 volts, you will be closer to getting the 50 amps for a longer period of time into your trolling batteries. Problem with these converters is they may select a lower charging voltage of 13.6 ish which charges the batteries much more slowly.
