I keep reading and re-reading about the Tesla pack on their website. This time, I caught a little error! Here's a quote from:
Battery | www.teslamotors.com
"Sixty-nine cells are wired in parallel to create bricks. Ninety-nine bricks are connected in series to create sheets, and 11 sheets are inserted into the pack casing. In total, this creates a pack made up of 6,831 cells."
Now: 69 (cells) times 99 (bricks) equals 6,831
But, if there are 11 sheets, that's 6,831 times 11 equals 75,141!!! At about 39 grams each, that's almost 3000 Kg. Since the pack weighs about 900lbs, maybe they just don't use the 11 "sheets" they talk about?
Here's what one cell can do

Edit: That cell is uncharged, straight out of a "dead" laptop battery pack!
