Hey guys. I just got started into vaping about a month ago and im ready to upgrade to a box mod. As of right now i have the Ke cig 100+ with the mephisto rda. The mod was great in the beginning but learning more and more about them and now the mod is very inconsistent. Unless its a fresh off the charger battery it barely wants to heat up (running a .2 coil build right now). Can anyone point me into the direction of a box mod for me. Here are the things im looking for. Able to run a sub ohm coil (.5 and lower) and dual battery setup. If yall need more info just let me know. thanks for the add on this forum
