Charging AGM batteries
I have never owned an AGM battery, but the new trailer I am getting will have 2 of them. I replaced the converter/charger in my previous RV with a PD4655V, and am thinking of installing the same i...

I don't know if it "overkill" to use the specified 14.5-14.9 voltage or whether they need that to get the acid up to required strength.
There seems to be one kind of AGM that specs 14.8ish and has limited spec charging amps (about 30%) while others (Lifeline eg) want lower voltage but will take huge amps during bulk. There are more types of AGMs too, like those UPS ones guys are getting, which the say you have to be careful to use their stated specs. (not as bad as GELs though, AFAIK)
I know many chargers and solar controllers that have Wet, AGM, and Gel settings have the AGM voltages set lower than the Wet settings. That seems wrong to me, since my AGMs specs batter match the Wet settings on those.
Adjustable chargers are the way to go these days.
I see these want 14.4 - 14.58 for charging. Don't have the amps spec if any.
