While the test results are hard data, the conclusions and recommendations I make based on these tests are only my personal opinion based on my criteria for setting a rating. Carefully research any cell you are considering using before purchasing.
Testing cells at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them.
If the cell has only one current rating number on it, or if it only says "max" then I have to assume that the company is stating that the cell can be discharged at that current level in any way, including continuously.

Bottom Line
This cell has “Max continuous discharge: 38A” on the wrap. While this is a bit of an overrating this is a great performing true 30A cell.
It appears to be a Samsung but it outperforms any Samsung I’ve seen in that capacity range. It might be one of the new generation cells being produced for automotive use.
While this Vapcell has a lower capacity rating than the VTC5A it holds its voltage up better at high current levels. This makes it about equal to the VTC5A in total running time down to 3.2V. The Vapcell hits a touch harder than the VTC5A at the start but the VTC5A runs for a touch longer. I’m not sure you’ll see a difference in actual use though. The Vapcell does run cooler than the VTC5A and this can help extend overall battery life when used at very high current levels.
It runs cooler than the HB6, and for a lot longer, making it a better choice than the HB6 for very high current use. This is a damn good cell!
While rated at 2000mAh, this cell only delivered 1912mAh of capacity at 0.5A down to 2.5V. I consider this the “typical” or “nominal” capacity. The rated capacity must be considered the guaranteed minimum capacity and therefore must be less than this nominal capacity. It is typically 100mAh-200mAh lower than the nominal capacity rating.
I am rating this Vapcell cell at 30A and 1800mAh.
I don’t know where this cell can be be purchased yet but vendors can contact Vapcell (www.vapcelltech.com or Shenzhen VapCell Technology Co., Ltd. - 18650 high drain IMR batteries,18650 charger/26650 chargers). The two cells that were tested were donated by Vapcell for that purpose. Thank you!

Comments
Vapcell paid a fee to be moved to the front of the testing queue, which currently has an 8-10 week backlog. This cannot influence my test results as they pay in advance and I don’t care if any company never does this, or donates batteries, again. My reputation is a lot more important than any battery donation or payment.
