Hey everyone I have a wellec elvt 2.0 and wanted to go out and get a new tank got the the kanger subtank mini the store owner said that the tank will only work if I use the 1.2 ohm coil not the 0.5 ohm that is standard. Anyways I've tried both coils and neither one will work I get a red light and an amperage reading on the battery. Has anyone else had this problem? Or any suggestions to fix this would be greatly appreciated. Thanks!
