Just saw some 18650 cells that claim to have 5.8 Ah. The Model S cell has 3.1 Ah. If that cell I saw was legit, it would result in a 160 kWh batter for the Model S. Something can't be right here. Tesla would be be using them if they would be any good. I really haven't done much research on 18650 cells. What is the standard these days?
