Jason,
Yes, the higher capacity train of thought seems to work best....opted for
the Concorde 9150T 2v bank....big thanks to Steve Bell for pushing me in the
right direction.
Thanks to all for feedback.....

If it's "survival mode" only, why do you need 1,200 cycles?! How many
hurricanes/tornados/riots are you getting around there? :)
The S-460 is a great battery, but it's rated for 1200 cycles to 50%. I
don't have a cycle curve handy, but you can probably expect about half
the cycles at 80% DOD.
Based on the price, it looks like you are talking about 8 of the S-460's
for 350aH @ 48V. Maybe go to 8 of the Concorde PVX-2580L and use a 50%
DOD factor instead. I'm not sure how that compares to the GNB price for
the same capacity. That also gives you the option for occasional deep
discharges to 80% DOD. The point is, it might be cheaper to increase
capacity and decrease DOD than to buy a "higher quality" battery that
can handle more cycles to 80% DOD.

Getting a few "survival mode" system requests...and of course they want
"no maintenance" battery bank.....I have to smile when I see them flop
around on the floor when I show them the GNB Absolyte
pricing......Surrette's ain't that much cheaper (about $2000 in this
case).... any one out there spec'd the S-460-AGM that can give me some
feedback?...looking for GNB- like performance (1200 cycles @ 80%dod
tested) for just a bit less money (or am I just imagining those are
oinking noises coming from above?)
