Funny thing is Tesla buy batteries from BYD for some models. MB, Toyota, Ford and others are also buying BYD batteries. Their blade battery has proven to be safer and better than anything that is currently on the market and the nice part is if one blade fails the whole pack does not need to be replaced or cells clipped and neutered just the individual blade swapped out.
Anyone underestimating China's manufacturing prowess is doing so at their own peril. I am glad I bought stock in BYD car and BYD batteries, it is up a good bit since buying it and when the US market inevitably opens that ship will come in big time.
