A high capacity 26650 cell that can deliver a good amount of current.












The two cells math nicely and capacity is nearly constant up to 15A, at 20A I stop the test slightly early due to temperature.
It looks like there is a problem with one of the cells at 30A
























[size=+3]Conclusion[/size]

This 26650 has a nice combination of high capacity and fairly high current, but the rated 20A is best done with a little bit of cooling.

Thank you for the test. This cell looks to be very close to the Shockli 5500,which I've been using in all but high current demand 26650 lights.

Mooch recently tested this impressive cell. His results are very close to what HKJ's testing revealed.

...This is a great performing cell that will give you more vaping time than any other 26650 I've tested recently if you are at 20A/60W or lower. At power levels above this the 4200mAh-4300mAh cells based on the YDL 26650D are a better choice.

The capacity for the two Vapcells I tested was 5870mAh and 5879mAh at 1100mA (0.2C) down to 2.5V. This is fantastic consistency for a China manufactured cell and they easily exceeded their 5500mAh rating......Two cells were purchased for testing by me.

I've been running 2 of these in a 3D Maglite with a ASF 800lm droppin for a while now.
So far so good.

These will definitely be my next 26650 purchase. Thanks as always HKJ

I attempted to acquire some more of these cells, and [FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]unfortunately it appears that they may be discontinued and replaced with the lower capacity, lower performing purple 5000mah cells (which are very high performers in their own right).

I believe these cells have been criminally overlooked, as far as I can tell, using HKJ's battery comparator, I have only found one single cell (32650 Soshine) that exceeds their capacity and performance under load.

Hopefully, my info is wrong and these have not been discontinued.

You may still be able to get the equivalent Shockli 5500mAh battery, from sources like Mtn Electronics. The PLB INR26650-55A cell that is under the wrapper of both the Vapcell and Shockli (and Keeppower?) has apparently been discontinued:

That is unfortunate. Good to see they are still available in form of the Shockli though, thanks for the link.

26650 has so much potential. I wish there was more interest.
