Hello, i have a vamo v5 with a 5ml aspire nautilus tank. I currently use it with a 3000mah battery. On my ego twists, which are 1600 mah, battery will last me a full day. With this battery, which is double the size apparently, the battery drains from 4.1(full charge)-3.5 in about 5 hours of vaping. (3.5v is when i was told to charge the battery) I go through about 5ml of liquid during this time. I just wanted to know if this was normal or if my battery is dying quick? And another question is whether or not a good charger will make a difference in your battery life. Thanks.
