I have 3 batteries and 5 tanks that I rotate through with different flavors. My question is how long should the batteries last before needing recharging. I can go all day across all 3 but the vape gets weak later in the day so I rotate 2 to charge. (I have 2 usb chargers as well) and then put the 3rd on to charge right before bed so I have 3 charged batteries each morning. I just ordered a 1100mah battery yesterday that should help the issue but is 1 day normal even though im using 3 batteries, or am I just hitting these things too much.... LOL
