COACH BATTERIES

[Michael]

Correct Don, I mistakenly used 8D diminsions in my calculations. So
we're looking at 1646 Cu In for two T-105's vs the 636 of the group-
29. And I'd call boony docking for a month a "special need". Mind
you, I'm not knocking the power/performance of the series/parallel 6v
battery system. Just the need for us "common" folk with "typical"
power needs. And being able to use what ever quanity battery bank you
need is also a benefit, 12v systems can be of any quantity. I'm
assuming people are adding up their requirements so they are matching
the need to the bank size.

Regards, Michael

sure how/where you got that 4003 for two.
