You're only getting 2 hours out of an 18350?! You might want to double check those batteries... That is absurdly low runtime.
Vega, I chain vape, otherwise I'm sure they would last longer. Also using LR cartos drains the batteries sooner. The batts are only 2 months old and come off the charger at about 4.1 - 4.2 or so. I was thinking the same and then saw other peeps getting the same time frame with heavy vaping. I run through 4 of these a day and that's with switching off to the KGOs onece in awhile.
