This is a very good 20A continuous discharge current (CDR) cell, equaling the Samsung 25R. At 25A it gets very hot. This is not a 35A cell and, in my opinion, you should not run this cell above 20A.
Comments
- At 10A the discharge almost reached 2800mAh, this is very good performance for a 2800mAh-rated cell.
- At 20A the cell had a higher-than-average maximum temperature of 82°C, about the same as the Samsung 30Q and LG HG2.
- The cell performed quite well at 20A, lasting a bit longer than a Samsung 25R but with very similar voltages under load.
- At 25A the cell reached a max temperature of 97°C. This is a way too high a temperature for a cell to operate at and is very close to my safety limit of 100°C.
- Discharges were not done at 30A or 35A due to the very high temperature seen during the 25A test.
- An additional five cycles at 20A showed no signs of damage other than that expected from running a cell at its CDR for several cycles.
- A second 10A discharge also showed only the changes in voltage and capacity normally expected after several cycles at the cell's rating.
- I am setting a CDR of 20A for this cell. I think you will get decent cycle life due to the minimal damage shown at that current level. It is a very good 20A cell. But, in my opinion, you should not run this cell at above 20A.
- This cell has a top shape very close to the 25R. The inkjet codes on the can are also similar to the 25R. But, it runs hotter than the 25R, and lasts longer, so I don't know if it's a rewrapped 25R or not. It certainly is a very good 20A cell, no matter which one it is.
