26800 will also discharge continuously at 25 amps. However this maybe the cell for those lights that can’s convert to 26800. Yes, the 26800 length fills my hand better.
Samples have been sent to HKJ
The improved version k62 has lower capacity, but more stable performance without self discharge

Thanks
Yeah，So re launch the new product
Thank you very much for your support of vapcell products
The red elephant battery is 26650 5500mah 20a, which has stronger power than k62
It seems that there are few sales in the market. Where did you get the battery?
I’d have to go dig up receipts but it would have been a US supplier…probably Illumn but maybe Liion Wholesale. They’ve been good cells. Not getting as much use over the last year since I converted most of my 26650 lights to the Queen Battery 26800 cells.
The Vapcell red 26650 5500mah tested the same as the Shockli 5500mah. They were the best 26650 in existence. Unfortunately manufacturers stopped making 26650 flashlights few years ago since 21700 cells came out. If we get a super good 26650, that would convince flashlight manufacturers and maybe other device manufacturers to start making 26650 products again.
Emisar D4SV2, Convoy M3-C, S11, L range, Sofirn SP33S. Plenty of good 26650 lights.
My D4SV2 and M3-C are now exclusively 26800 lights :nerd_face:
Thrunite Catapult V6 and Lumintop ODL20C V2 also new 26650 releases. Looks like Lumintop went with 26800 for the new D3, though.
26800 is where it’s at for fat cells. It offers more than any 26650, still, although it sounds like this new 26650 may be a great general purpose choice with more capacity for replacing cells or in lights that can’t (or don’t wanna be) upgraded with longer tubes or adapters. For new lights, it makes the most sense to go with 21700 or 26800 though. In the nonflashlight world there are still plenty of devices that were designed for 26650 (and cheapie flashlights, too) so they’ll need good cells as well.
But those lights come with their own branded 26650 cells. I do wish there is a 7000mah 26650 with 20A. Then I would be all for 26650 flashlights.
26650 batteries with 6800mah 10A can be made. The unit price will be very expensive and the market will be very limited
It is expected to exceed the wholesale unit price of $7
Developed by Samsung and molicel, it is estimated that it can do 7000mah 20A
I don’t expect to wait for it in my life 
10A won’t cut it. That won’t be enough to motivate flashlight manufacturers to hop back on to 26650
Can I use them in my Convoy L6 ?
If you can find them. I checked yesterday and they don’t have them listed on their web site anymore…
Here you are.
Thanks. I was looking at their web page as linked in the OP.
One would think that they should have them…
Anyway, thanks for the link!
I would like to report having self-discharge and overdischarge issue with possibly some Vapcell K62 26650 batteries, based on my purchase of 8 pieces of them.
I purchased 8 pieces of these Vapcell K62 2600mAh 26650 from a local reseller.
All of them arrived properly sealed/shrink-wrapped.
I tested the voltage of all of them.
- 4 pieces arrived at around 3.77-3.78v
- 2 pieces arrived at around 3.66v
- 1 piece arrived at 1.10v <= OVER DISCHARGED
- 1 piece arrived at 0.79v <= OVER DISCHARGED

I reported the discharged batteries to the local reseller, and the local reseller asked if I can use reactivation charger to charge the 2 pieces over-discharged batteries.
I was able to charge the 2 over-discharged Vapcell K62 (monitoring the batteries temperature when they were nearly fully charged)
(For the 6 pieces batteries (3.78v and 3.66v), I left them as is and did not try to charge them yet — I plan to observe if their voltages may continue to drop.)
Now for the 2 pieces, after I “reactivated” the over-discharged batteries, I did a round of capacity testing (charge to 4.20v, discharge at 1Amp to 2.50v), and the results are 6208mAh and 6057mAh
After finish charging, I did not use the batteries but left them unused on the table at room temperature (room temperature here is probably around 30 degrees Celsius)
very fast self discharge for one of the over-discharged batteries:
- tested voltage (a few hours after charging) … 4.125v
- 32 hours later … 3.849v
- another 14 hours later … 3.66v
from 4.12v self-discharge to 3.66v in around 2 days.

for the other over-discharged battery, it appeared to be a bit better:
- a few hours after charging … 4.170v
- 32 hours later … 4.159v
- another 17 hours later … 4.151v
(I think this may still be considered normal? will observe a few more days)
