I have a ego c twist that has a full charge of battery. if i use it with my vivi nova mini, i can get a full drag with it. But when i use it with my carto tank, it cuts off and it will blink 5 times. This also happens even if the ego c twist has a full charge. My carto tank is a cheap dct smok tek tank with a smok tek 1.5ohm carto.
