I hope someone can help me understand what's going on with either my batteries or mod. About 2 weeks ago I noticed that my batteries in my Minikin 2 were full and by the end of the day it was half full. 2 minutes after I saw that it was half full it completely died on me. I kept using the batteries for about a week but it kept doing the same thing. As soon as it became half charged it would just die. So I figured these batteries are pretty old, it's about time I buy new batteries anyway. So I bought 2 brand new Samsung 18650 batteries. I charged them until they were full and put them in my Minikin 2. It barely lasted me 1 hour. It was fully charged and then it was dead. It didn't even show that the charge was getting less and less. So I don't know if it's my batteries that are acting up or if it's my mod that's killing my batteries. I never had this problem before and I've had my Minikin since August. Anyone else experience anything like this before and know what the problem is?
