Hello everyone! I just got a Kanger Subox Nano kit the other day and I've noticed the tank gets pretty hot while I am vaping. So I was wondering if this is normal and also if this particular model has any safety features? Do I need to worry about it short circuiting or anything? I have the 0.5 ohm coil in that it came with and a (green INR18650-25R Samsung SDI) battery that the Vapor Shop said it needed. I'm charging the battery in a multi cell battery charger instead of using the cord that the kit provided, so I can swap out batteries. I have the Ecig 20.0W and I'm using Betty by Pinup Vapors in 6MG/ML. Is there something that I'm doing wrong? Thank you for taking the time to read my post and I appreciate your help!
