    To make the 18650 ratings table more consistent and prevent some of the confusion I was seeing I recently changed my continuous current rating for the Samsung 30Q from 20A down to the manufacturer’s rating of 15A.

    This has its own problems as the rating in my table no long reflected this cell’s great performance. After reviewing the datasheet I have decided to extend the 30Q’s rating back up to 20A...conditionally.

    The Samsung 30Q datasheet (Section 7.9) mentions operation at 20A. Operation at that level can be done as long as we don’t let the battery get above 75°C, its maximum rated operating temperature.

    This keeps the ratings to what the manufacturer sets but allows operation at up to 20A, which was what my rating previously did. This is not a perfect solution but it’s the one I have now. Sorry for the confusion all this has caused. The tables will always be works-in-progress and I will continue to try to keep them useful tools for vapers.

    The 18650 ratings table has been updated to reflect the 15A/20A rating this cell now has, along with the Sony VTC6. The LG is still rated at 20A continuous.

    I will be posting a “shootout”, directly comparing the performance of these three cells, within a few days.

    Thank you for explaining this. :)

    I was initially disappointed when you changed the 30Q's rating from 20A down to 15A. I understood why you did it, but the 30Q is perhaps my favorite battery. I only use these under 40 watts in a regulated mod, so I wasn't abusing them. Still, it seemed a 15A rating wasn't doing this great battery due justice. A lot of folks might avoid this battery just because of the 15A rating, but if the user isn't a high wattage vaper (say under 40 watts), it may be the best battery for them with the 3000mAh capacity.
