What we are sure of is that the largest battery pack as of this writing will be less than 100kwH. The sizes 60,75,90wH has been mentioned in other posts, and I will use these as the examples. What if Tesla configures the battery packs to be made in a 60kwH size and then 15kwH size increments. If you order the base Model3, you get 1 battery pack. If you order the 90kwH, the car is fitted with 3 battery packs. Tesla is offering Roadster owners a battery upgrade, but from what I read it is a complete replacement. People who are stretching to purchase a Model3(or deem that 60kwH was enough at the time of purchase) can decide in the future to book a servicing and add 15wH more for a price plus install. Would that be viable, or are current owners wanting a brand new battery pack, and not interested in adding a new smaller pack to their older battery?
