The Samsung INR 18650 25R is an excellent battery cell for vaping. Its strength is to be both a high drain battery as well as a large capacity battery cell. Battery cells are, either, great at delivering a high Amps discharge in bursts or at delivering a large capacity over a long period of time - but not both. The Samsung INR 18650 25R is good at both and delivers a perfect balance of power and capacity that is ideal for most vapers.
If you are a big "sub ohmer" and need the highest discharge possible - we still recommend using the Sony VTC4 18650 2100mAh 30A battery cell. Otherwise, for the vast majority of vapers, the Samsung INR 18650 25R would be more ideal.
These batteries are powerful - if you do not understand how to properly handle batteries - do not buy them.

Batteries week right away
I've bought these same 2 brand of batteries 4 separate times.  Every other time, the batteries start off strong and once charged can last a day, day and a half.  The last ones that showed up are not strong.  Installed one in my Pico and it can only make it a few hours.  When you pay $10/battery they should be brand new and should last longer.

back up
My battery is only 3 months old but I'm realizing how important back equipment is in the vape world. I would rather buy one here at a great price then shop around town when I need one and pay a higher price. Peace of mind.

works as it should, real deal.
Couple dollars more than some places, but came in an actual Samsung box w/o sticker over the print on the wrapper. Running my pico like a charm.
