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 Eizfan cell is identical in appearance in performance to the 15A Sanyo NCR20700B.
This cell has a truly ridiculous current rating of 30A and has an overrated capacity rating too. There is no reason to buy this cell if you have access to the Sanyo NCR20700B. I am rating this Eizfan at 15A and 4000mAh.
Two cells were purchased by me for the purposes of testing.
Continuous-Current Test Results
Pulse-Current Test Results
No pulse testing was done as this is a Sanyo NCR20700B rewrap.
