So I've been using a 650 & 1100 mah Kanger EVOD for the past 4 months, successfully quit with these. Also reducing my nic level every 4 weeks (not entirely by choice, this is a work issue). These workhorses are really my adult pacifiers, constantly in use-I'm allowed to vape at work, and do so freely. Sometimes I'm hitting it so regularly it gets hot at the connection point. I assume this is not a good thing, so what's my options, well besides the obvious putting it down. I'm wondering if a different battery or atomizer would perform better under these chain vaping conditions? Also, I need a third battery. I won't charge mine while I sleep, and more than once I've woken up to 2 dead soldiers and resorted to a cigalike until CPR/battery recharge occurs. I also really don't want to change from the single coil EVODs unless there's a good reason to do so. Advice?
