Tested at 5A-15A constant current. This cell was purchased by a friend from IMRBatteries and donated for testing. To prevent any confusion with the eGo-type "batteries", I use the term "cell" here to refer to a single 18650, 26650, etc.
Disclaimer
The conclusions and recommendations I make based on these tests are only my personal opinion. Carefully research any battery you are considering using before purchasing.
Testing batteries 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. My safety precautions are the ones I have selected to take and you should not assume they will protect you if you attempt to do any testing. Do the research and create your own testing methods and safety precautions.
Bottom Line
This is a great 10A continuous discharge current (CDR) high capacity cell. At 15A its temperature is close to my safety limit of 100°C. In my opinion you should not run it above 10A.

- At 10A the discharge reached over 2600mAh. This is great capacity for a 2680mAh-rated cell running at its CDR.
- At 10A down to 3.2V this cell beats both the MH1 and MJ1. Of the 10A high capacity batteries I've tested, only the NCR18650GA 3300mAh beats it.
- At 10A the cell reached 65°C, a low temperature for a 10A cell being run at its CDR.
- At 15A the cell had a high maximum temperature of 92°C. This is too high to set 15A as the CDR.
- An additional five cycles at 10A showed no signs of damage.
- I am setting a CDR of 10A for this cell. It runs too hot to set it at 15A but the temperature is low at 10A. I think you will get very good cycle life at 10A due to the low temperature at that current level. In my opinion you should not run this cell at above 10A.
