The high current capabilty is good on these cells.
The two cells does not have exactly the same capacity and without protection this makes them best for single cell usage.

Thanks for the test.  The timing is perfect.  I need a higher current 14500 and I only have one good 14500, and that doesn't even do 3A.  Good advertising for IS too.

The low mode should be lower.

It seems others are silently reading this review.  The 18350 version is already sold out.

The low mode should be lower.

Inventory was inaccurate. I usually reduce the number we actually have online to make a buffer.
