(Not that I begrudge them for having good strategic partners; Apple doesn’t manufacture the iPhone, Amazon doesn’t manufacture the Kindle).
Tesla's battery slideshow showing their new battery that supposedly has 50% more energy also happens to be that much larger. But for what ever reason their marketing people thought it would be ethical to make them the same size on the slides.
