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 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 cell is accurately rated at 20A continuous and 2500mAh. I am delighted to report that while it features a useless “pulse” rating on the wrap it displays the continuous and pulse ratings equally.
This cell’s physical appearance and performance are essentially identical to the Samsung 25R2 but all of the 25R variations are so close in appearance and performance I cannot say for sure that the SubOhm is a 25R2 rewrap. There’s a chance it could be a 25R5, 25R6, or 25R6M.
It has a wrap that is thicker and tougher than the stock 25R wrap and should hold up to abuse better. As with any thicker wrap though be aware that it might affect how this cell fits in mods that are already a tight fit with 25R’s.
I am rating this SubOhm SE cell at 20A and 2500mAh.
The two cells that were tested were purchased by me from SubOhm (www.subohm.com).

Pulse tests were not done as this is a rewrapped 25R
Comparison to the Samsung 25R2
Always Remember
⁃ There is no 18650 with a factory/manufacturer rating over 30A continuous.
- There is no 3000mAh 18650 that can have a rating over 20A continuous.
⁃ There is no 3100mAh-3600mAh 18650 that can have a rating over 10A continuous.
⁃ There is no 18650 available to vapers that has a capacity rating over 3600mAh.

Comments
- At 10A continuous this cell delivered a bit over 2400mAh. This is good performance for a 2500mAh rated cell so I am rating it at 2500mAh.
