Tested at 10A-35A constant current. This cell was purchased from RTDVapor 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
In my opinion, this is a good low-capacity 24A continuous discharge current (CDR) button-top cell. I recommend not using it above 25A.

- At 10A it reached about 1500mAh. This is pretty good performance for a 1600mAh-rated cell.
- At 20A the maximum temperature reached 68°C. This is low and indicates that the cell is not yet operating at its CDR.
- At 25A the temperature rose to 78°. This is average for a cell operating at its CDR.
- At 25A it's capacity down to 3.2V is only a bit less than the LG HD2. It runs longer, but hotter, than the LG HB6. If you require a button-top, this is a pretty good hi-amp cell.
- Five additional cycles at 25A showed only the normal loss in capacity resulting from operating a cell at its CDR. But there was a bit more voltage sag than usual, indicating that the cell was being damaged a bit at 25A.
- At 30A the temperature rose to 85°C, too high for setting the CDR at 30A.
- At 35A the temperature rose to 94°C, way to high to operate a cell at.
- I am setting a CDR of 24A for this cell. Its temperature at 25A was moderate but there were small signs of damage after the additional five cycles at 25A. Dropping back down a bit, to 24A, will help slow down that damage. While operating any cell near its rated maximum current causes damage to the cell, I would expect decent cycle life from this cell at 24A. I would not recommend operating this cell above 25A due to the damage it causes.
