The cells tracks good between them, but there is a small capacity difference.





The temperature is not bad, even at 10A.















Conclusion

This cell has good high current capability, but do not get it if you want a lot of capacity.
It looks like a good cell.

Thanks for the test, I was waiting for this one.

In a quick glance they have slightly less capacity than its light purple predecessor, but keep a tiny bit more voltage at high current.

10A performance is good coming from an 18350. Capacity is meh.

Because my 18350-based flashlights draw less than 3A, I’d probably select a different cell - depending on price.

Thanks for the review!
