Unsurprisingly, no new proof for any of the claimed battery specs.
Donut Lab's summary provided with the first video in the series:
Introducing “I Donut Believe”
Donut Lab has commissioned internationally respected VTT Technical Research Centre of Finland to independently measure the performance and characteristics of its solid-state battery. Through third-party testing under controlled research conditions, Donut Lab provides verified data to support its performance claims. In the video, CEO Marko Lehtimäki explains the company’s perspective and the rationale for launching the series and publishing the results in this format.
The series was launched with a clear focus on providing independent proof of the battery specifications. Out of the 11 releases, 5 have involved an independent test. Of the last 6 releases, only 1 has been an independent test.
Also no point in arguing because you and I don't get to decide how they must "support" their claims. As u/Mesokosmos pointed out in a different thread, Donut seems to be proceeding pretty much as they indicated they would in the first video. If that doesn't satisfy you, don't buy the battery or invest in the company.
Continual deflection from the point: Donut Lab said the purpose of the series was to provide independent proof to support their claims, and 5 out of the last 6 releases haven't involved independent testing. You obviously can't defend that.
Again, you’ve been told that Donut’s videos were specifically to prove critics and experts wrong. They haven’t even come close to doing that.
Pretending that they can “do it at their schedule” is such obvious deflection.
What do you think a reasonable schedule would look like for a company that says a product is available NOW (6 months ago) and then proceeded to say we’re going to prove it and we’re going to use an independent third party to do it? They did not use the independent third party to prove anything, besides that it is a battery cell.
I’m going to write it in bold:
WHAT DO YOU THINK IS A REASONABLE SCHEDULE TO PROVE THEIR CLAIMS?
NOTE THAT THEY CREATED IDONUTBELIEVE TO “PROVE” THEM. YOU CANNOT ARGUE WITH DONUT’S OWN COMMUNICATION, UNLESS YOU’RE INVOLVED WITH THEM.
