Efest has made a range of very high current batteries (Purple), this is the 18350 sized one.










The cells has very good tracking between them and does also handle the load very nicely.















[size=+3]Conclusion[/size]

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

Got them recently, but mine are V2 (button top) ones. One cell measures 640mAh, and another - 740mAh, using LiitoKala Lii-260. Will test again using Turnigy charger...

Is there a review of v2?

The main difference between V1 and V2 is flat or button top, the cells are supposed to be the same.

The easiest way to find a review is to check here: http://lygte-info.dk/review/batteries2012/CommonSmallcomparator.php
There you can also easily see if there are newer versions of the reviews.

Thanks. I don't know yet if I need button or not for the new Manker I bought. I think all that is available at illumn is v2.
