How can you charge two+ batteries simultaneously?

[THE]

Can you charge them in series or is that as seriously bad of an idea as I think that it is??

Can you connect two-three (or even more) batteries in parallel to a charger?? I'm assuming not, since the charger would always think they were way the hell over charged, right?

I'm assuming that there has to be _some_ way to charge multiple batteries wired in parallel ... simultaneously through one wire ..

Actually now that I think about it ...... wired in parallel the charger would see the _average_ voltage of all the cells - - is that correct? Is that okay?

Any ideas would be great, thanks

just get a multi cell charger, You can also buy what is called a hobby charger but those are used more for balanced charging when you are using multiple batteries in either series or parallel in Remote controlled cars,planes, and boats

Is there a safe way to charge them without take them out of the e-cig device... that's what I'm thinking (sorry, I should have been more clear)

Not in most mods, especially mechanical or semi mechanical mods.

I was thinking about making one... that's why I wondered about this.. Apparently, lion cells will equalize up when they're sitting there wired in series?? Is that right? What about while charging?

Also, how would I get a charging circuit that would do it right?

I honestly don't know if they equal up when sitting when in series. Easy enough test. All you would need is a voltmeter, test seperately before and then put them in series and test after sitting. My guess, no they don't equal out. You cant charge them in series though, at least with our chargers , wrong charging voltage.

I agree, in my mind, they would never just equal up together UNLESS they were all wired in parallel and even then I would doubt it..

The only way I could think of to charge several cells simultaneously through one wire would be to have them all wired in parallel... then it'd work, right? The charger would charge until it saw the 4.2v and then stop?? If you have 4 cells and cell 2 and 3 aren't fully charged, though, but the 1 and 4 were ..... 1 and 4 might keep getting charged which would be very bad... I think.. right??

Sigh.

Could use a multi channel charger and run a fat 8 conductor wire but good lord imagine how it'd have to be wired, inside, and it'd have to be switched somehow for use in series and charging in parallel

geeze

And I don't know how to make circuit boards

But I know that they make battery packs with multiple cells in them .. for all sorts of things .. lion especially .. and THEY can be charged all at once, so how do those do it???

Well, here we go, but I'm not sure if this explained things or
Multiple Li-ion cells parallel charging - Charging End determined by what?

 

[THE]

Apparently I could get a balancing charger like they use for lipos ??? For limn??

My thought would be to put a switch in there from "charging" to "on" .... that'd kill two birds with one thing .. the user couldn't inadvertently try to charge and use it at the same time .. and "charging" could double as "off"

I think I need something like the BLINKY ... I remember my sister and brother in law using that for the LIPO batteries in their rc racecar things


Now here's this guy saying limn doesn't need balancing http://www.rcuniverse.com/forum/m_7898973/anchors_7903883/mpage_1/key_/anchor/tm.htm#7903883

This is going to take a lot of reading
Sigh

I've been into RC's for over a decade, and thats the first time i've read about charging Lithium @ 2A and being told not to balance the cells...

TBH the thought of someone misinterpreting that info scares me.





to the OP, just get a proper charger... I've seen 4 cell chargers that charge the cells individually for just over $20.
Super T has the TrustFire TR003 (which i own) and it does the job...

I'm sure it is not that much work to remove the cells from a mod so that you can charge them....
