All i can tell ya is that i used them in that nem you sold me & i got nearly 2 days vaping per battery with no signs of anything unusual. Keep in mind though that i'm no different many other people with regards to battery education & bought them entirely at my own risk... Ug ! Me guinea pig !!
Oh yeah, i'm NOT sub ohming. More like 1ohm & 1.4 ohm.
If I'm not mistaken these are NCR 18650B Panasonics, Max Current 4a, on a freshly charged battery of 4.2 volts you absolutely should not go below 1ohm which will draw 4.2a or 17.4watts
