Tesla whistleblower Martin Tripp is tweeting internal emails, photos and vehicle identification numbers that he says are evidence of flawed manufacturing practices at Tesla's battery factory, and product sold by Tesla that is imperfect, and could put drivers' lives at risk.

Tripp has, in previous interviews, said that Tesla's Gigafactory took dangerous manufacturing shortcuts, and that Elon Musk had direct knowledge of these and failed to intervene.
