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...

One can buy a group 27 starting battery and find it weight under 50Lbs

One can get a 115Ah rated group Marine group 27, and find it weighs only 56 Lbs.

One can get a group 27AGM and find it only has 91Amp hoours and weighs 68LBs
Same exact case size, 16 Lb weight difference, yet the lighter battery is rated at higher capacity.
Having cycled 2 of the batteries in the above example, The 68Lb AGM is the clear winner In deep cycling longevity, and starting, despite the near 150% extra cost.
Yet claims thin plate, but pure lead plates.
The ONLY flooded battery I will ever consider using again in my rig, is the trojan t-1275 scrubber battery.
I might get a chance to test a once extremely overdischarged and otherwise abused, Firefly Carbon foam group 31.
