Elon just tweeted this: @danielringdahl @P100D Glad you like it! I think we will probably stop at 100 kWh on battery size. Really? On the one hand I see the logic: if the goal is to bring down price, you want to use better chemistry to make the pack smaller and lighter and cheaper while holding capacity constant. On the other hand, I think there's real value in getting from the current 300 mile range to more like 4-500. Maybe in the future we can have a dual battery option instead of a bigger single pack?
