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 Vapcell is identical in performance and appearance to the great performing (for low power vapers) Samsung 48G cell. Samsung rates this cell at 9.6A continuous.
Vapcell, why rate it at 20A continuous? It becomes hot enough to boil water at that level and the voltage sag is huge. Simply inexcusable.
I am rating this Vapcell at 10A and 4800mAh.
Unfortunately, this cell has Vapcell’s usual paper top insulating ring so juice spills could damage the ring. Be careful.
After seeing the first posts of these test results Vapcell informed me that they will be changing the continuous current rating to 10A and switching to a plastic top insulating ring. They said they will send me the updated cells for testing then. If this happens I will post the new test results.
I expressed my anger that this was only happening after being caught exaggerating the rating so badly. But, it is a positive step and one that many other companies would not take. In the end, what is important is that we have our cells accurately marked.
Two cells from Vapcell were donated for the purposes of testing. Thank you!
Continuous-Current Test Results
Pulse-Current Test Results
No pulse testing was done as this is a Samsung 48G rewrap.
