Choice of converter for AGM batteries
I plan on replacing my Trojan T-125's with 3 (or 4) x Lifeline 12v AGM batteries @ 215 A/H for a total of 645 (or 860) A/Hs total. I want to use the 12V batteries since I dry camp 90% of the time and ...

Pay attention to lifeline's recommendation to charge at .2C for repetitive deep cycling. None of the chargers you're looking at meet that charge rate.
I'm using a PD9280 with 600AH of Lifelines, and I have my batteries set up in 2 banks of 300 so if I charge just one bank I can hit them with .27C (not including any solar input).
Every day use I just connect both banks and let the solar maintain them. After doing that for a while I can see the batteries getting lazy from slow charging so once a month or two I separate the banks and discharge one at a time and then charge it hard with the 9280.
