Crap!! Will update - rushing at work... Those erroneous quotes will live forever! 
Yikes! There seems to be lots of bad cells around lately
Dennis: Please, if you could, explain a bit of what going on with quality as of late? What's the testing process?
I had a sneaking suspicion the K64 would have QC problems. Especially since 1. Vapcell does not own their own factory 2. Nobody else is producing a battery with these specs.
To their credit, it has to be tough to design and manufacture a new high discharge cell with increased capacity.
The F14 doesn’t seem to have the same problems probably because only capacity increased. Probably easier to rework existing technology to increase capacity but not both at the same time (high discharge + increased capacity).
Hopefully the F14 stays around, great for Convoy lights since they can’t pull more than 3A.
I ordered some batteries from Vapcell 101 days ago and still not received…last tracking number update was 47 days ago…
And they still want me to wait 
Fair enough if you chose the cheapest shipping option, maybe chose an alternative for a higher cost
They don’t offer any alternative for me, only $6 option.
Interesting, I had a bunch of Vapecells arrive yesterday 2 of which were K64’s and they were perfectly ‘storage’ charged. 3.76v & 3.84v. I drained one down to 2.8v then charged it and got well over 6k mAh’s like 6250mAh. The vapecelll INR21700 4200mAh cells which are the Mollicel 4200 30A continuous discharge had a clear wrapping over the cells which I thought was clever protecting the contacts. But so far I like those K64 cells and the little 18350’s with 1400mAh tested well (T14), I measured over 1400mah when charging but are only 4A. But to be honest I’ve been pretty happy with Sofirns cells like their 4K/5K 21700 and I have a bunch of their 18650’s which have been decent. Much cheaper too.
Having unequal storage voltage shows there’s still a voltage instability problem. Every single Samsung, Panasonic, Sony, and Molicel have been exactly the same voltage across 500+ cells.
Roughly 40 of the 120pcs Vapcell K30 that were okay in my order were a solid 3.71v, the other 80pcs were 3.68v+, and the remaining were even as low as 1.78v (got a refund on 20pcs of the worst)
I guess the best we can do is:
I wonder how safe it is to run lithium-ion batteries with a high self-discharge rate. I know that some chemistries have a rather high self-discharge rate but I only saw these in NiCd or NiMH cells before. A lithium-ion battery is a whole different thing, I guess.
BTW, I have (among other batteries) six K64 batteries incoming. They are probably still en route to Europe or being checked by customs (who knows). I will be happy to carry out steps 2 and 3 and report about their status as soon they have arrived.
Do you mean F14? I can’t find a T14
Hopefully Vapcell reworks the K64. I don’t need it but I want it.
Wow the K64 is incredible! Thanks for sharing!
Yes they’re Green, F14 is right.
Any idea where they were purchased?
If I am not mistaken they were bought from Vapcell‘s AliExpress store.
K64 sucks… After ~two weeks of non-use have 2.04V and 0.20V!!! 
Sitting inside or outside a device?
Too bad. I had high hopes for this cell.
It certainly sounded decent, but unstable voltage isn’t good. First on my K30’s and now hearing this, their QC sounds like a real issue at the moment
Outside
Are you able to get a refund?
I hope so, but I just opened a dispute
