Yeah, you will notice a serious drop in power. Mine usually drops at about 3.5. I normally replace them at that point. But, if I am in a situation where I can't swap batteries(driving) I know generally about what volts I am sitting at. So I can continue to vape. I just have to adjust my style. I normally draw the vapor in my mouth then inhale. But when the power drops that method does nothing for me. So after about 3.5 I swap to a lung inhale, not as satisfying as a fresh battery, but in a pinch it gets the job done. If I continue to use this method after 3.5 I will notice another drop in power. One in which I can not get any satisfying vapor out of it. Generally that is about 3.2.
Normally I swap at 3.5 but, even with 20 batteries, you find yourself unable to swap batteries. I don't record that you make a common practice to do this. But it is nice to know that I can. I have yet to drain a battery past that 3.2 mark.
