I use 18350s. I know you're not supposed to use them until they're completely discharged. My coil is 1.4 on the multimeter. When should I change batteries? I don't want to put myself at risk of anything a few times a dayhow do you guys judge when to change?
Thanks everyone
You will notice a drop, I find most of the time I don't like the vape after it hits about 3.4. So when you notice it go ahead and meter, but it is better not to run them lower than 3.2 if I remember correctly.
