[A/S] OTG in a/s and furnace draw was: Re: gadget geek in an Airstream

["Maurice Riggins" <maurice.riggins@xxxxxxxxxxxxxxxx>]

A pair of T-105s in series has the same amperage, and as a result, 
amp-hours, as a single T-105, 225AH at a 20-hour rate, which is 
11.25A.  All you do by putting them in a series pair is double the 
voltage.  As long as you don't exceed that discharge rate (with a 
light or two), you can count on that many AHs.

T-105s can be discharged down to 20%, but they'll last 3 times longer 
(i.e. have 3 times the number of discharge cycles) if you keep that 
to 50%.  If you do that, a pair of T-105s in series will run the 5.5A 
furnace continously for about 21 hours before the batteries are down 
to 50% of their capacity.
