Speaking of batteries, my new Nitecore D4 and 4 new LG HG2s arrived today.....how long should it take for this to charge 4 batteries from nearly dead?

About 10 hours if you charge them 3 or 4 at a time. Half that 2 at a time.

It's gonna take a while. I have the same charger and when you charge 2 batteries it goes at 750mah, with 3-4 it charges at 375 mah.
It takes quite a while to charge my hg2's in my d4 but I charge them at night.

obviously. But mAh is a measure of current capacity, while Wh is a measure of power. As your equations point out, both configurations will deliver both the same total ampacity and wattage. But 3x voltage will deliver it (assuming the same resistance) in 1/3 time. This is true because 3kmAh@11.1v=9kmAh@3.7v.
Ok, but its still 3000mAh. ;)

I know Watt hours is not really battery capacity, I wasn't trying imply it was, its the energy equivalent to 1W of power used over 1 hour of time. I was just pointing out for our purposes you can compare 3 batteries in series vs 3 batteries in parallel using Watt hours to gauge a mod's effective run time (total power/energy stored).

I think we're on the same page here, other than its not 9000mAh, and I'm not trying to be argumentative, just trying to answer @haleysdadda's question.

That is not correct actually. Three 3000 mAh batteries in series is still just 3000 mah.

As you pointed out because they are in series the nominal voltage is 11.1v, so it is effectively the same thing as 9000mah at 3.7v (nominal voltage) considering Watt hours.

3000mAh * 11.1V / 1000 = 33.3Wh
9000mAh * 3.7V / 1000 = 33.3Wh
To get on this again, I don't want to quibble: you are technically correct. I interpreted the question differently than you. What OP wanted to know was how long the batteries will last in his normal usage pattern. The answer is 3x as long as 1 battery. The whole thing points to the fundamental stupidity of rating batteries in Ah to begin with. Rating them in Wh, as you did in your equations, makes a lot better sense. Obviously, amperage is important. I harp on that with noob vapers all the time. But amp-hours isn't important, it maximum safe amperage draw continuous that counts. Anybody not conversant with the equations you posted will understand it a lot easier if the same batteries were rated 1.1Wh and 20CDR. That tells them what they need to know without a lot of fancy math in the middle. Just a thought.

I agree. We cross posted and I said much the same. I don't disagree with you at all. But I did interpret the question differently than you.

So it's ok to leave them overnight?

Just moving into chargers, have just used cables thus far...

You will never catch me recommending somebody charge Li cells unsupervised. That said, I do it all the time.

Heh, well at least between the two of us, he should have a good understanding of his battery life with 3 cells.

All I know is it lasts longer then my old mod with 2 batteries in it lol.

And that's the bottom line. @ThunderDan and I both said the same thing in different ways. Yours, perhaps, is clearer than either :)

I tried a bunch of random juices today on the stainless steel claptons and got interesting results.

A lot of juices that I really like didn't taste good at all. It had a funny taste to it. Only thing different is the coil material, I used the same cotton as always.

I tried my kanthal claptons and everything tasted great like it did before.

I'm gonna put the SS Clapton wire up for sale on the local Facebook page and go back to my kanthal claptons. I don't know why but for some reason when I try new stuff I don't like it. Native wicks cottons, rayon, SS claptons. What the hell is next???

It's only been running for about an hour and a half and it's pretty warm. Dunno if I trust it overnight on my desk. May be better in the kitchen on the granite....

I keep mine on its side so it can breathe thru the back and the one side. I've had mine fall over on its back once and it did get pretty warm so I always charge it on its side. I've been doing this for about a year now and haven't had a issue since

Technically the Wh are the same between series and parallel mods as Dan pointed out. In general though, series mods tend to have higher efficiency. However, I know Yihi says the sx350j will give higher efficiency and longer runtime in series below 75W. I don't have any information on any other chip as far as efficiency ratings on using it wired in series vs in parallel.

Basically, there's not much difference and probably not enough to be noticed.

Rewicked my MT build for my mech, I misspoke yesterday, its a 6 wrap 22g dual coil build.

Low light with this camera on my backup phone is great. /s

It works really good and I charge a lot of batteries in that charger. My Vape batteries every day, Xbox one batteries every other day, Wii U batteries every other day and my sons train batteries all weekend long. That charger has been rock solid for me. Sure it would be nice if it charged 3-4 batteries at more then 375mah but its been reliable.

I can't say the same for the luc v4 charger I ordered and that charger supposedly isn't safe to charge AA and AAA batteries in because it charges too fast.

When I switched from kanthal to Ni200, my juice tasted weird at first. It took a couple of days actually to become accustomed to the different flavor. A few days after the switch, I threw on a STM that still had a kanthal build and it tasted terrible. The experience was similar when going from Ni200 to Ti, though that was just more of a pure improvement in flavor.

While everyone's taste is subjective, I think several that have switched to Ti/SS/NiFe will agree that kanthal and to a lesser extent Ni, adds it's own flavor to the juice when being vaped. There are juices that I used to like, probably due to being masked/changed by kanthal, that I didn't like when I changed to Ni/Ti because I was getting just pure juice flavor. I read some DIY'ers lowered the flavor % because the flavor was too strong.

The change from cotton to rayon had a similar effect... once wicked correctly, rayon added no flavor to my vape like cotton does - again, at least to my taste buds. But if not wicked correctly, rayon can have a very nutty/earthy flavor.

Just a thought, but you're taste may be so used to kanthal that it would require you to vape through the difference for at least a couple of days. However, if you enjoy what you're vaping, that's all that really matters!

Well, that was interesting, if not particularly amusing. I was going to re-coil the Fishbone in Stainless, as I mentioned yesterday but, once I got it off the machine, I say my Vector laying handy and-- the fishbone is annoying because it likes to puke juice out of the air holes, I really don't like bottom air drippers-- and the ol' Vector has been begging me for a set of quads ever since it got here, so I though today was the day. So I built a set of quads, put it in the vector, had it all neatly measuring .3 ohms and was doing the heat-and-squeeze trick to tighten up the coils, when I promptly burnt one of the wires. So, I built another set of quads, installed them, and burnt that one out too. It seems Mr. Snow Wolf-- he's an Old Skool V1-- recognizes stainless wire as TC, even though I intended to fire it in watts mode. But on the SW, that's not selectable: if it senses TC wire, it defaults to TC mode and there's no way to take it out other than put a Kanthal coil on it. It's too late to build another set tonite, so I'll try again tomorrow, using the SX Mini. Or maybe I'll wait until the RX200 gets here. I really don't understand why the SW does that; it was built before SS wire was used and it is (I thought) a strictly Ni200 machine. But if it defaults to TC mode, and has the wrong temp coefficient, I guess it will burn them out. (sigh)
