Charging a Battery Bank
I am planning on upgrading my batteries to 4 6v batteries wired in series and parallel to have a 12v system with plenty of Amp Hours. There is a ton of information on how to wire things up but nothing...

BFL13, forgive my ignorance but what does Vabs mean? Also, where do I find the voltage specs? I checked the .pdf duracell has for their 6v AGM batteries and I don't see any mention of what they should be charged at. With 190 amps total in a 2 battery duracell AGM setup and for sake of argument, lets say I'm charging when batteries are at 50%, at what amp setting would be reccomended with an adjustable version Powermax like you have?
Here are the Deka charging specs

There is no amp setting. You buy a charger with a certain amps limit like 60 amps or 100 amps. Note they say charging current limit is 30% of AH capacity. Two 190 6s is 190 12v so charger limit is 57a.
14.1-14.4 AGM spec allows for a PD 60amper (does about 57 at first then tapers a bit) if you go that route.
Vabs is the Absorption Voltage. (I got that Vabs from an Iota blurb ISTR) It is the "high set point" voltage. The voltage the battery rises nearly to with that charger's setting during the Bulk stage and then amps taper from there while the charger's Vabs is held constant --the Absorption Stage.
