Can I charge 2-18350 batteries in a charger meant for a 18650?

[purelyscientific]

I have a charger for an 18650. Can I stack 2 18350s in it to charge them?

Here is the charger I use- http://www.discountvapers.com/18650-3-6v-li-ion-dual-battery-charger/

Not only no.......BUT HELL NO!!!!

 

[purelyscientific]

Care to elaborate?

Is there risk of explosion???

 

[jkmtwo]

Others will chime in shortly Im sure, but that would be dangerous, think about it logically, you are asking a charger designed to charge a battery from about 3volts or higher, to 4.2 volts, and now asking it to double that voltage

 

[purelyscientific]

Wouldn't that just mean they would charge slower?

Is there risk of explosion???

Yes, that's why they make 2 bay chargers.

Dude (smh)...

It is a 2 bay charger. Its just meant for 2 18650s

Thoughts?....

Stacking batteries in a mod is not all that safe to begin with,,but stacking them to charge them ?? NO !!

you can charge those 18350 batts in that charger,just use a spacer,,roll of dimes or pennys works fine..

Great Idea. I didn't think of that. Thank you.
Now I don't have to spend extra money for a second charger.
(I assume pennies would be better- lower res)

The thing is- from what I've read- is that I need 2 18350 batts to get the most power out of my Vamo and that I can't get full power from just one 18650.
It has short circuit protection and a vent hole just in case. Would there be risk of explosion if I used chemistry safe batts?

Sorry guys, I'm new to mods and these might be noob questions. I appreciate any help you have to offer.

I use 18650 Panasonic IMR's in mine and have plenty of power.

You can use 2 18350 IMR batteries, or a single 18350 IMR in short mode. A single 18350 IMR gives plenty of power, just not a very long vape time.

IMR's are "safer chemistry" batteries, so they aren't supposed to explode, but you still wouldn't want to stack them to charge them.

 

[denali_41]

under beat me to it

if you plan to vape under 4volts or 7watts ?? you probably won't even need to stack batts

i've done the watts thing and the hype just isn't there for me,,at 9watts and above, it was just nasty

 

[purelyscientific]

at 9watts and above, it was just nasty

You mean burnt tasting?

I have a dual coil carto that won't work good on my eGo twist even at 4.8v
Hopefully it will work better on the Vamo I'm getting tomarrow morning.

I'll try my best here.
That charger is designed to charge at 4.2v. Two 4.2v batteries will be in series, this means the voltage is doubled, so they want 8.4v now. In parallel they will take the same voltage, but want more amperage. Series is + -, parallel is + +. Series, more voltage, same amperage, parallel, same voltage, more amperage. With me so far?
IF you do plan on using stacked batteries, it's best to keep them in pairs, mark them! This way they wear the same as you cycle them. Using a brand new battery with an old battery can cause a problem. The newer one wont be restricted by the crystallization that happens to batteries with normal use, limiting the current delivery. Other wise the new one will be pushing hard, the old one can't keep up, so the new one pushes even harder and "boom" can happen.
Have a read through this, it should help some, I hope. Basic to Advanced Battery Information from Battery University

MOST are running single coil cartos now ..i hated then DC ,,everything tasted like puke to me

The IMRs (safer chemistry) are recomended for the VAMO as they can handle the amps needed to give you full power. In VW mode the VAMO can pull more wattage than protected li-ions will provide without being damaged.

... not quite true. AW 2600mAh Li Ions are more than capable of providing the current required. it is just that folks use IMRs.
