Doesn't sound fair, I see what you mean now. Think it's just easier for them - not 1 person can directly control each order charge like Simon can. Weight does matter but it's not a direct ratio with cost.
What is fed sales tax?
Ooops, it's all state and county.
@vapcell Dennis
Any update on Samsung50S or Vapcell T50
@Tom E, How is K64 if you compere to Vapcell T50 I think you have it too
I’ve got a few K64 Vapecells coming, U wonder who actually makes them & whether there sold under the original brand.
I received 2 pc K64 last week and one has 3,67v, the other one has 0,3v ... so one is dead on arrival.
I used the good one in D4sV2 and in Ni40 and it is very similar to the Shockli 5500 and I get round about 6000mAh into by a Start of 2,95 to 2,98v. So as my first resume the good one is a good Battery but do not reach more kapacity like the Shockli in the first attempts.
I would like to see, what Vapcell say to the DOA battery, but no answer yet now....
Hhmm, don't think I have a head to head. Should do one.
K64 is not available to order anymore. On TLF I noticed another member reporting that two out of two K64 batteries were dead on arrival with 0.7V and 0.74V.
Ouch! I got 2 good ones - weird.
Got two on order from the Vapcell ali-store, not send-out yet. Let’s see what happens 
Vapcell, can you check my order?
I ordered 1lot(8pcs) Vapcell K64 from Vapcell/AliExpress store last April 3, 2021.
I was given this tracking number, but later changed to another tracking number:
RB635245138TW & RB753931767TW,
but both these tracking numbers do not show any infomation on tracking websites.
Did some simple tests last night, but not long timed testing. Just in initial amps on a FT02S (quad XHP50.2's) w/mods, all cells charged to 4.21V:
Shockli 5500: 22.8A
Vapcell K64: 26.4A
Samsung 40T: 30.5A
Vapcell T50: 31.0A
On a MF01 Mini, brass w/mods:
Vapcell K64: 24.1A
Vapcell T50: 27.2A
On a HK4S (quad SST-40) w/mods:
Vapcell K64: 21.2A
Shockli 5500: 18.0A
So the T50 is much it's superior, but the K64 does well against the Shockli. This is just turn on amps, somewhat indicative of what it can do, but an initial 30 sec test, plus a full timed run would be a better comparison.
After my issue with the Vapcell K30 I’ve been put right off.
120pcs were fine and 39pcs had high self discharge. Charged all 39pcs and after just 5 days some were just 4.12v, a cell from the 120pcs was still sitting at 4.192v.
Very decent performance at a good price so it’s rather disappointing
Has that 40T also been modded 
37.2 amps? :-O Jeez…that one must have become pretty hot within a blink of an eye.
Now, I will regret for the rest of my life that I ordered two pieces of the T50, only. :-D
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.
