Hi Guys,
When I am home, most of the time I am using my Totally Twisted VMU which runs on two 14500 batteries. When I flip the switch on the inside, the voltage indicator reads out the voltage of the batteries. So when I have two freshly-charged batteries in there, the unit reads 8.4 volts (4.2 + 4.2) and as I use the unit, the max voltage slowly drops in 0.1 increments. I have a battery voltage chart which says that 3.5V = 0% battery life. When the max voltage gets to 7.0 (3.5 + 3.5), I take out the batteries and put them on the charger. But since I vape at around 4.8V, I was wondering if I can just keep using the batteries until max voltage reads 6.0V? I don't want to over-drain the batteries, but I thought that 3.7V LiOn batteries are fully discharged at 2.8V, not 3.5V.
Somebody please explain this to me. :-(
Thanks,
Emile
