Indeed, Tesla has always had a superior BMS, and I keep hearing that they have a custom electrolyte or something that Panasonic uses for their cells? They seem to get 2-3x the lifetime out of similar cells. The Leafs don't have liquid cooling, and that's the only reason why I won't buy one - it's both bad for battery life, and fast-charging (Leaf owners call it Rapidgate).
