Chris brings up an good point. There does seem to be some confusion , at least in my case, about the difference between the "LiFe'' batteries and the "A123" sytems batteries. My understanding is the A123 company developed the lithum ion technology and then marketed them as "A123" a trade name. This may or may not be true. So confused as I am , it's off to Google .

From" A123 Systems" website is this quote " A123’s products are built using our breakthrough Nanophosphate® chemistry, a proprietary form of lithium iron phosphate (LiFePO4)"

This information helps me a little but still does not completely clear up the confusion. The batteries I use are the flat pack LiFe that Hobbico markets, available from my LHS. I believe the "Real" A123 are only available in cylinders.
So CHris you are probably right. We can continue the discussion when we next meet. Looking forward to KY jets. Hope to see you there
