hey all...thanks for reading. So i started using e-cigs over 2 years ago by buying a joye ego-t system which worked great with the ce2's (i think...the ones with plastic tubes sold in 5 packs and held about 1.2 ml of juice) but i cant find these any more so i switched to the ce4's by uno vapor which seemed to have no hit and hardly any 'smoke' so i went to vivi nova 3.5 system which is terrible cause it has no hit and seems to use double the juice the ce2's did. The batteries i use on these are genuine Joye ego-t 650 mah (1 month old) manual batteries and i was wondering if these aint putting the volts out needed to run ce4 and the vivi nova 3.5. I read that these batteries usually put out about 3.2 volt but on a digital multimeter it shows 3.9 after taking it off the charger. I just order 2 1000mah eco-c twist hoping this will take care of this problem and was wondering if u guys think i made the right choice...thanks for reading
