    Top notch as always...

    ...and a great price. If you buy on ebay the odds of getting counterfeit crap batteries is higher than Surefire prices. These are the real deal that are SAFE to use and backed up by an American that lives in the great State of Florida. Just read his educational sections so you know you are getting the right product for its intended purpose, especially when it comes to Protected and Non-Protected cells.

    The Legend for Sub Ohms builds

    Posted by Joel on Dec 9th 2016

    Best and safest for Sub ohm mods below 0.2A.For standard vaping duties that don't see loads below 0.4 Ohms I use the INR1865025R because it lasts longer.
