Finances must be getting dire to worry about $1 batteries. Why are you so wound up about it?

I'm not wound up about it.  I want to know if my educated guesses are based on decent logic.  I thought ecig people used batteries and were capable of math.  Seems like I see battery stuff and math stuff here, but maybe that was wack, and I should check out Facebook or Instagram where the experts are.

Aw, mj. I can pretend to be WillyB if you want, but I'll have to go read your question first.  I'll get back to ya ASAP.  I have stacks of those batteries so I've never tried to get a good deal on an eBay purchase.

I'm sure they're based on decent logic, you're not a dummie. We both know that you won't know about the quality of the cells until you break it apart. It's just the way it is. It's a cheap gamble though. They could all be awesome or could all be ultra fires.

The ebay thing is just an example of something I'm looking into for a couple reasons.  It isn't about being cheap, per se.  The quality of the cells can't even be guessed by opening the pack and looking at the wrapper either, you fuckers know this too.  You actually haveta go full flashlight geek to do that.  Yeah, kinda like WillyB.

Thass alright Kase.  Didn't really mean to direct my snipe right at you, I was pissed at a manipulative human bio-dad at the time.  If I decide to build lightbulbs ever again I'll be looking for your posts.

I'm not sure your assumptions regarding correction factor are true or able to be proved.
I THINK you're looking at 4 batteries in series with 3 parallel sets at 2200mAh per battery.
But just a best guess.

I came to a similar conclusion, doc... 3 sets in series, each set consisting of 4 cells in parallel. But that puts nominal voltage at 3.5 volts, which seems low to me. Made me think I was way off so I didn't say anything.
Fuck you and your piece of shit troll forum.

Yeah.  I do think it is really harder than that.  But I don't think they actually boost or buck in those packs.  So at that voltage one of those numbers should be close to correct.   I think these will be functionally equivalent to individual batteries marketed at 2400 mah.  I think I bought the exact same thing 1.5 years ago, used the fuck out of them, still have some in use in flashlights and mods, and the kid must have snagged at least 2.  The real question is how well they will hold up in my death ray and time machine.

Just a quick question....how the hell do you break the frames on these posts?  It's annoying as hell.

I remember on Something Awful breaking the frames gained the poster probation and a snotty comment from the mods.
(Reading just the leper colony posts is entertaining.)
 

Glad that doesn't happen here.  8)

Yeah, sometimes I go back and edit them when it gets really stupid.  Usually it's just a really wide embedded pic or a really long string of text, like mj posted.  Not too hard to do, but pretty easy to fix with a DEL key.  You can go back and add height and width tags to someones image instead of deleting it if you are feeling really nice.

I haven't been to SA in a while. I used to hit the Book Barn pretty hard after a GRRM novel would come out... and the Goons are always good for the griefing lulz in almost any game out there. Those dudes crack me up.  I like to think of us as a baby SA sorta.  I come here more to laugh than to learn about fake smoking.  Same with SA.  It's all about the comedy.

TITFA. Is it really worth buying and cracking a laptop battery open? Do you really need twelve 18650's?

Here's high drain, 35A, 2500mAh, purple Efests for a buck a piece.

Considering a "Vatic" is named after Vatic, I'd say Vatic.

Do you really need to post here?  Is it really worth your dignity to suck all that vendor cock for free mods?  Is it really worth my tax money for you to live on welfare?
