If that cell underneath the wrap offers the same current specs like PowerLongBattery's PLB-55A cell (see Shockli 5500mAh or Keeppower 6000mAh), it would be really awesome.
At least I am most pleased to hear that 26650 battery development has not ended yet. PLB has given up producing the PLB-55A battery last year, so the only powerful 26650 battery left is Golisi S43 with only 4300mAh.

Is this available from US dealers? My last 26650 search didn’t see it.
is this really legit the capacity, i thought 6000mah was the max this type of size could hold ?
Theoretically it’s about 7100 mAh if using the same guts as a 3400mAh 18650.
Is this the highest capacity constant discharge on the market for 26650?
VapCell 26650 K64 6400mah 15A/25A
Is this the highest capacity 18350 on the market?
Vapcell INR 18350 F14 1400mah 3A
I wonder when US vendors will be getting both in stock
Me too, hope it comes to US. 26650 walking lights are my go to. I live in the boonies and like high lumens for my aging eyes. Long run times with this cell would be great.
And I see a new high capacity 18350. I prefer higher discharge current at this size so I’m not in but still I am happy to see an improvement in this format. 
Ordered a pair of the K64's from your Ali store - Thanks Dennis!
Can they ship batteries without a flashlight?
Always have. I dunno - I ordered batts from them like I always have, many times.
Had an order of batts in Dec, 2 orders in Nov - all went well.
Good to know. Let us know how the K64 preforms. I’m really glad they didn’t give up on 26650 cells.
The K64's finally arrived at home - hope to charge them up this eve.
Update:
Charged up the cells, and based on the starting level and how much mAh's they took, the capacity sounds about right. They also performed well in running some simplistic tests, measuring initial amps on some higher powered single 26650 lights.
Still want to do capacity tests on my chargers, two SKYRC MC3000's. The GOLISI's are not new, but shouldn't be heavily used, but still may not be a valid comparison, and limited test of simple initial amps.
Appears so far to be a solid candidate for best all around 26650 cell, great capacity, excellent performance.
I’m pleasantly surprised. I was certain that greater capacity would suffer in output. To actually get both capacity and amps is a good jump forward.
Thanks a lot for testing Tom E! I am surprised that K64 even surpasses the PLB 55A cell underneath the Shockli 5500 wrap, being so close to the power of a Samsung 40T. Since the 21700 battery makes more spring compression in the MF01 mini, the K64 battery could be even in line with the 40T if contact resistance is disregarded. This is fantastic news, especially since PLB once announced they would discontinue their 55A cell. :-) I look forward to seeing your capacity tests.
Maybe HKJ can also do some tests under heavy load (10A, 20A, 30A).
Highest capacity and highest drain in the same cell? A dream has come true? Would be even greater if the capacity is somewhere around 6500-6600 mAh.
Is it still not possible to consolidate shipping fees on the Aliexpress store ? last time I asked they didn’t want to. So we have to pay 3.98USD of shipping per item…
If I order 2x L10 shipping is 3.98, if I order 4x L10 it’s 3.98, if I order 2x L10 + 2x H10 it’s 7.96 even though it’s the same weight as 4x L10.
Thanks

Nice! My capacity testing may have to wait til the weekend. Let us know if you do any more testing.
For me in the US on the Ali store, if I buy, 4, 6, 8, or 10 K64's, I pay only $2.11 for shipping. NY State (and fed) sales tax is steep and Ali charges it, so for qty 4 and above, NYS sales tax is higher than shipping.
You don't have the same options on the Vapcell Ali store in the EU? Maybe this is a new option?
Granted, these are not cheap, for sure. For qty 6, it's a total of $67.37 total for me.
From 1x to 10x K64 the shipping is 3.98 here, but what I was talking about is when ordering different cells, let’s say, 1x K64, 1x M11 (18350), 1x M35 (18650), then shipping is 3x3.98= 11.94, despite weighing way less than 10x K64.
And Vapcell doesn’t want to recalculate the shipping cost, unlike Simon/Convoy for example, if you order 10 different small items from him he will recalculate (if you ask him) an appropriate shipping cost instead of charging shipping for each item.
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.
