This is a 26650 cell with fairly high current rating.

[size=+3]Conclusion[/size]

This cell do very well up to 20A, it can also do 30A. The capacity is not in the top and that could not really be expected from a high current cell.

I was just looking at these a few days ago and couldn't find any information on their performance. Thank you for your review.

From the looks of it, the Vapcell 26650's (5000mah purple, 5500mah red) are still the highest performing 26650's on the market.
