They haven't said a peep since CES over a month ago where they very quietly talked about their battery, no big fan fare. They seemed to be keeping a pretty low profile, it was all the YouTubers that started a huge hype train. That drove a lot of understandable skepticism, and now they're getting third party tests done to settle the question, no doubt because some investors got nervous about all the skepticism.
I think if they were doing so then there would not be much point in trying to market to the internet at large.
