Yeah.
And … that would be, eh, let’s try to re-wrap it politely, something about moisture and people you dislike :)?
Oh my god we should have chosen a different domain name in the first place :).
But I am glad that we could contribute some entertainment, too ;). As I said, a more international domain name that will redirect to an english version of the same site is on its way.
What I can tell you is that EFest IMR 14650, 18500 (flat top) and 18650-1500 are the well-known “BDL” aka “BIO” IMR, technically unchanged (proven by measurements, not all of them posted yet though) but now with EFest branding.
As for EFest IMR 18350, 14500 and 16340, these are different from the former BDL/BIO types. Optically, aside from the EFest branding, the positive pole has changed.
The EFest IMR 18350 “flat top” (raised flat top actually) outperforms the BDL/BIO IMR 18350 and can now be stacked, is however still not as good as the AW IMR 18350:

However, EFest is coming up with button top versions of some of their sizes, and the EFest IMR 18350 “button top”, on the other hand, performs worse than the EFest IMR 18350 “flat top”:

The rather new EFest IMR 18650-2000 however performed reasonably well. We will be able to show graphs soon.
The SMR IMR outperformed the AW IMR in 14500 for instance - yes.
But no, they are not publically available and probably never will be. They were made according to my own spec for me by a battery factory as a “proof of concept” that good value for money is possible (IMR 14500 was 2.30 EUR, IMR 18350 2.50 EUR, IMR 18500 3.40 EUR and IMR 18650 3.70 EUR) for a group order at our German vaping forum.
