How low of voltage do you let your battery go to before changing it? I noticed with the RM2 and a 2.5 coil that my battery doesn't drop as fast as when I was using cartos. With cartos I lost good vapor hits at about 3.8 or 3.9. But not with the RM2.
The battery information I have read for the AW IMR is to not discharge below 3.5. You will gain the longest life for your batteries if you recharge before 3.5v. They will also perform better if not discharged lower.
I generally recharge mine about 3.7.
Me too! I really have to watch the VV's batteries though. I have gone lower on them and not realized till I pulled and metered.
Hmm.. I just go by taste. Once the vape becomes a little 'thin' both strength and tastewise (don't know how else to describe it), I switch out the batteries. It's easier to do instinctively with the mechanicals. With the provari I just vape until it starts blinking at me.
With the mechanicals I've checked it a couple of times, and I usually end up around 3.6-7 volts when I recharge.
