Has anyone tried to make a battery for automotive use?

Samsung 18650 INR18650-25R 2.5Ah
http://www.ebay.ca/itm/321609228901

I came up with this Idea how it would look like in SketchUp. It should be just under 7lb with 55Ah (I'm guessing it will have 770MCA & 484CCA). I have 4 in series & 22 banks in parallel. How does lithium-ion do in cold weather?

PS: or maybe have have 3 INR18650-25R's in series... 12.6V Open Circuit Voltage (fully charged)

I don't have much technical know-how, but know these cells are not going to like the hot and cold much (both really hot AND really cold where I live). Plus the life cycle is around 250 I believe, so you may not even get 1yr out of it depending on how often it's charged and used.
