INR21700-40T - Are they all the same?

[Robin Becker]

Just read on a thread in the German Forum that Samsung SDI apperantly changes dome details in the datasheet of the 40T: Samsung INR21700-40T - Seite 5 - Mountainprophet

On the one hand it seems like the weight of the battery is reduced from 75 Gramm to 70 Gramm, but on the other hand the CDR is now even raised to 45A under thermal limitation.

My question is mainly to Mooch, but maybe the others here would have an answer as well?!

Is it possible, that the INR21700-40T is a different one from the 40T that were tested so far?

Did anyone has more information on that?

Have you seen this @Mooch ? Interesting

Because all 40T are still preproduction samples, I doubt it that these are the same cells.
And since the above datasheet is still "tentative", I'm pretty sure that Samsung will change the cells again.
So until they decide not to tweak the 40T any further, we're their guinea pigs.

This Datasheet is not a tentative, but was placed by Rutzki73 from Enerdan on the Forum. He also added the old datasheet, which was a tentative and showed the differences between the old and new datasheet...

This is the only datasheet I know of:

INR21700-40T.pdf

Same data, but still tentative.

Usually when a datasheet is approved, you would find the name of the person on his signature as well as the version number, or number of approval etc.
In the case of the datasheet you linked to, Version is 0.0 and no person is signed on it...

Well, it's from Akkuteile.de

Samsung is finally starting to release the production version of the 40T to some distributors/customers. There are some changes in the latest version of the datasheet.

I will be receiving samples of these production cells and will compare them to the performance and appearance of the pre-production samples I tested earlier.
