Stress on IMR Battery Question

[pdib]

How low is a safe drain on a IMR? I thought 3.2 volts, but I just read somewhere where it was saying the 2.2-2.5v rang.

You'll stop using a battery at about 3.5-3.8. So if you're worried about over draining while vaping, its not going to happen. (with mechanical, that is)

You don't use 4.2V with a calc like that. You need to determine the actual, vaping volts while under load, then use that number + your measured resistance to determine the AMP/current draw and vaping watts.



For all you subΩ 18350 users the AW IMR18350 seems like a much better choice over the Efest.

The AW sags less and maintains a higher voltage longer. If you put a pencil to it the AW will be providing about ~12% more watts than the Efest.

All that book knowledge is fine and what. My anecdotal input, based on actually doing stuff, is that the Efests are outperforming the AW with no room for doubt.

that's comforting, I have 8 18350 from efest on the way They had a 2 pack at 8.40$ and now it seems to be even cheaper, free shipping worldwide.

Kinda what I figured since the vaping power would be gone long before it got to 3.2v anyway... but I figured I'd ask incase I got caught out without an extra and had to deal with it and run it super low, lol.

Book knowledge? LOL

You seem to have a hard time understanding actual empirical data based on real tests.

It's comforting to ignore actual tests while relying on this?

anecdotal evidence has been defined as

"information that is not based on facts or careful study"
"reports or observations of usually unscientific observers"
"casual observations or indications rather than rigorous or scientific analysis"
"information passed along by word-of-mouth but not documented scientifically"

Good luck

Uh oh, DSmooch. Looks like you're headin' down a baaaaad road!

no no, not ignoring, I'm just trying to convince myself it wasn't such a bad deal... I got some 14650 efest, they're not so bad. considering the AW 18350 were 10 bucks a piece, I figured I made THE deal. but sure, there's always a catch I guess...

Uh oh, DSmooch. Looks like you're headin' down a baaaaad road!

and what road would that be? LOL

 

[pdib]

the "felt comforted by anecdotal information and now you have (scientifically) the worst batteries in the world" road

 

[DSmooch]

yeah, definitely hasty... all cool now, I feel bad again.

wow!!...huge sag with the Efest at 20 samples..?
