I ordered the first battery skeptical because of dealing with other sketchy companies in the past. This first battery and transaction was perfect by all means, above and beyond my expectations. I ordered a second with the same experience. This is my go-to company for all my battery needs going forward.

I am ecstatic. Tesla batteries I received are like brand new. I don’t even think they’ve ever been used they look that new. Very happy customer.
