Samsung 30Q 18650 3000 mAh Battery

Needed high discharge current batteries for some specific application (not vaping) and I'm very happy with Samsung 30Q.
When fully charged under the load batt voltage is dropping to 3.7V and stays at this level long enough to fit my purposes.
Delivery was very fast, thank you! But packing could be match better - just dropping batteries in the bag without separating them is not the best solution.

Very quick delivery. Always a pleasure dealing here!

The 30Q batteries are working well in terms of charge life. However these batteries and other brands I have tried don't seem to last that long as far as number of charging cycles.
The device I am using the batteries in might be the issue here as the battery sits right next to the heating chamber.

Perfect.no surprises at all.thank you so much

I waited until I had actually used them to write this review. I am very familiar with the characteristics of Samsung 30Q batteries and believe that these are genuine. Best price!

Very happy, I purchased the vape some time ago and had my first puff the other day,good amount of Vapor,very happy with it so I purchased two spare batteries to take me when I go to areas with no power

It worked on my arizer air, very good stuff.
