Thanks for posting this find!
These are likely whats under the Vapcell T50, which has proven to be a killer cell.
Has it? I’ve never heard anything about them except for manufacturer’s claims.
wait i thought 50G is the upgraded version of 50E
Who has it it in stock?
Users here have experienced them delivering amps like a 40T. TomE is one I remember off hand posting about them.
Same here. Have not seen any comparison tests to the Samsung 50G or 50E.
Vapcell’s website shows some tests. I’m not sure who did the testing but it looks promising when compared to the Molicel P42A.

Are you sure? It’s a brand new cell, it’s pretty unlikely anyone got it yet.
No lie. He got some from what must have been some of the first ones to get sold. His arrived on Nov 10th. Here’s his initial impressions:
And some pictures he posted:
Over at TLF toobadorz provides more measurements and comparisons to other 21700 cells:
Kind regards

I’d love to see comparison graphs between 50S and 50G.
Wow the performance is insanely good!
Does this mean a 30Q killer is also on the way? I hope so.
I can vouch for the Vapcell T50's -- outstanding!!
I got mine direct on the Vapcell store on Ali: https://www.aliexpress.com/item/4000579178671.html?spm=a2g0s.9042311.0.0.51fa4c4dt8NhPg
I ordered a pair twice so got 4 of them. Should have tried them in my modded TK90 which take 3.
They look amazing but the cost is quite high, plus the 3 month shipping from Vapcell despite their high shipping price is pretty discouraging.
I hope we’ll see them distributed by local sellers soon.
3 months? Not for my orders. Last pair ordered Nov 21st, delivered Dec 12th - 21 days.
Local availability will most likely improve in 2021… and the price will come down significantly in 2 years when Samsung releases the 60Q. 
I don’t think 60Q will be a possibility. The 18650 couldn’t break 3500mah for half a decade already. 21700 is maxed out at 5000mah.
