I am sure this is a stupid question

Ok, so I have no experience with mechanical mods, only vv/vw devices. So on a mech mod, how do you know when the battery is around 3.0v and needs to be recharged? Especially if one is running sub ohm
Like I said, this is probably a stupid question

Get a multi-meter. They are cheap enough...10 to 20 bucks...and when working with sub ohms and mechs, I'd say you can't NOT have one.

Not trying to be funny, but depending on the battery, you will notice a drop in warmth and vapor production, or the device will just stop firing all together. +1 for the multi-meter. Must have

I have a multi meter, it is what I use when rebuilding. So if I am out and about with a mech, I am just going to guess when I think the battery is close to dead?

 

[devlindchi]

Ok so the power drop will be noticeable. That would work,

 

[StarsAndBars]

Yeah, sorry man but that's kinda how it is. After a couple of days you will kinda learn how long the battery will last, and be able to expect the power drop. That's why I strayed away from my mech mod. For the most part it would last me all day but not always. Nothing sucks worse than a dead battery when you can't get to a charged one for a few hours.

It doesn't take long to get a feel for when to swap them out. At this point I rarely check voltage on batteries I think are ready to be charged. When I do check them they're almost always somewhere between 3.7 and 3.8v, sometimes as low as 3.5v.
