upgrading power converter
My power converter has apparently bit the dust, lights flickering for past couple of years now no charge to batteries... Anyhoo, we do a lot of dry camping, where we need to daily boost the batteries...

The confusion seems to be that you are talking about voltage and I am talking about amps. Not sure about that though.
They go hand in had. If you have full amps your voltage is going to continue to rise until either the set point is reached and the amps drop, or your voltage rises until the internal resistance is too much for the amperage and stops rising.
It takes amps to make voltage, which I am confident you know.

The data are:
inital current 61.5A
after 1 hour 60.5A
after 2 hours 59.4A
after 2.5 hours 57.5A output voltage now up to 14.0V so I suspect it will taper faster now.
after 3 hours, 43.4A, and output voltage is at 14.3V and 84% SOC
after 3.5hours, 32A and 90% SOC
So it basically held the 60A output for 2.5 hours before beginning to taper.
How does one know it's at 90% SOC while it's charging? 32A charge rate seems like it would be at less than 90% SOC, but???

No, I want the current to stay at 80 from start up till battery voltage reaches 14.4 (in PD case), not drop right off like Fisherguy's does.
I have only had the ammeter for a little bit, but I have not noticed the drop in amps prior to the voltage hitting 14.4 on my PD4655. It appears to hold 55A until the voltage hits 14.4, and then tapers the amps to maintain 14.4, as it should.
I will watch more as the season goes on.
