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.

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:

I’d love to see comparison graphs between 50S and 50G.

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.

Local availability will most likely improve in 2021… and the price will come down significantly in 2 years when Samsung releases the 60Q. Wink

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.

Even further back, the 3400 was ~2012 or so?? So they increased capacity 2.9% in 8 years? It's slowwww goin with Li-Ion advancements in the real world. They've made better gains in lowering resistance, but you still have to sacrifice capacity.

I just recently picked up eight of them from Vapcell (rebranded as T50), but looks like they are sold out on their Ali store at the moment.

When did you order Rayoui? I managed to get a pair but it seems it has not even shipped yet after 2 months of waiting since November 2020.

That’s odd. I ordered on December 8 and they were delivered January 6.

I contacted Vapcell's customer service. They asked me to be patient as it will arrive eventually.

Moreover, they have extended AliExpress's timeframe to raise a dispute.

So, instead of 75 days I am now obliged to wait 90 days before I am allowed to file the dispute. Flat Stare

Photos from agents

There’s no mass production yet

So it’s more appropriate to buy Samsung 50g or 48x, 40t temporarily Smile

I ordered 30th December, still not shipped. No idea when they will be either as they have not responded to my message.

Thinking of grabbing some 40T’s for my K1 and K9.3’s… prob better then my 30T’s or 50E’s.
