Genuine Samsung INR18650-25R 2500 mAh Battery
With a 20 amp max continuous discharge this battery can handle sub-ohm builds down to .22 ohms (at your own risk).
However, where this battery really shines is when used to power a VV or VW mod. Our experience so far has been that this battery significantly outlasts the high current drain king of the hill Sony 18650VTC5 when used at the current levels (5 amps and below) that most VV/VW mods are limited to. If your VV/VW device (other than a DNA-20/30) can use flat top 18650s, then this is the battery you need !
