So, Im using two 18350 batteries in my vamo v3. When fully charge the vamo says something like 8.2v for the battery power. The vamo gives me low v and stops working when it shows around 6.4. Ive understood that a single battery is 4.2v. The vamo can run on one battery correct? How does this work. Confused and bad with this stuff

Each battery is ~ 4.2 when fully charged. If vamo says 8.2, that would ~ 4.1 x2. If it goes to 6.4, divide by 2 you get 3.2 which is about right for a recharge.
I use an 18650 in mine, though now it is only used to build rda's and check voltage.

Bad with batteries and stacking may be harmful. Pair the batteries and rotate them in the mod each charge. Make sure to label the 2 A and B. Charge them at the same time. They are now married and not of the swinger type.
Yes, I'd recommend you use an 18650 instead of 2, 18350's. One battery is always safer than stacking 2 batteries, jmho.
Cool, noted! These have always been used together and always charged at the same time. Did not know about the switching which ones goes first in the tube each time. I can assume ive done it on accident multiple times but not sure. I think ill look into getting one 18650 and a new charger since apparently I have the charger and battery combo that likes to explode in my kit anyways =-(
It's perfectly fine to stack two 18350's in the Vamo if you follow bluecat's advice and the fact that the Vamo has a protection circuit. Only two stacked batteries in the Vamo will allow one to get the full potential of the device due to the need for the Vamo to "boost" the 18650 battery. This may not be important to some, but to others, you can tell the difference between the two options.
I'm not one to recommend stacking batteries, even for mods "designed" to use them.

If you do choose to stack batteries, make sure you know the proper methodology:
I recommend using only AW IMR 18350 batteries. Protected NCR/ICR batteries do not have the high drain output that IMR batteries have. Do not use any battery with the name "fire" in it. Use the best charger you can afford: Pila, Xtar, and Nitecore are the most often name brands recommended.

If you do choose to stack batteries, make sure you know the proper methodology:
- The batteries used to stack must be "married" or "permamently paired" when new and clearly marked to identify them to stay together. (A1 and A2, B1 and B2)
- Rotate the order that they are placed into the mod each time you use them. They drain at different rates depending on the order they are placed. The intent is to have them stay as equal to each other as possible. A weaker battery of the pair has a much higher chance to fail and go into thermal runaway.
- Stacked batteries need to "rest" for at least 30 minutes after being removed from the mod before being placed on a charger. The same holds true when removing from the charger.
- Always check the voltage coming out of the mod (at least 3.4 volts) and coming off the charger (no more than 4.2 volts).

Don't say battery stacking is bad, you'll get all the Reo owners riled up.
I agree I also don't stack but you'll hear lots of opinions.
Acckk, Sorry didn't mean stacking was bad.. but the combo of being bad with batteries and stacking is a bad combo. Almost anything is safe as long as you know what you are doing with the right precautions. Heck imagine the Wright Brothers.. You want to do what??????
I personally haven't found a need to stack.
Exploding batteries terrify me. Fear is good though. Just remember these batteries are little packs of high energy.
It's not worth stacking batteries, even in the Vamo, which is designed to allow it.
The protocol (nicely outlined by Baditude) is strict and the penalties for breaking protocol can be quite ugly.
It's also not very cost effective, as even the very best 18650 battery cost less than two 18350's.
You definitely want to replace that charger and both batteries if they're the components in the twin-18350 kit with the wall mounted, single LED charger. They can go boom.
Nitecore, Pila and XTar chargers are all good. And an AW IMR flat top 18650 is a stud horse in the Vamo.

Using two batteries allows more power output. If I didn't need the extra power, I would not stack batts in the Vamo. If I didn't know if I needed the extra power, I would not use two batts. Just not worth the extra risk for no gain.
Honestly in in the vaping world we're quite lucky, our batteries are relatively safe. I've been flying quad-copters and Helis for the better party of 9 years. I've seen things blow up mid air and people actually set their houses on fire by accident, Here is just what one bad cell could do, heck even a good cell that was dropped by accident could spark and lead to major trouble.

Awesome! Ill do some research tonight. Would you mind if i shot you a link before i order anything. You seem to be my battery savior and your blessing would ease alot of concern before I pony up the cash. Thanks!
Holy Sierra. What was that guy thinking by shoving a sharp object into a battery pack like that? What did he think would happen?
That also illustrates another risk associated with stacking batteries. If you do have an unfortunate incident in the mod with a pair of stacked lithiums, when one goes thermal, the other one is almost guaranteed to flame out, too. Now instead of one little 18350 getting angry and hot, you've got two fired up in a sealed metal tube with limited venting capability.
Even in devices designed to handle a matched pair of good batteries, and even after following a strict safety protocol, this risk isn't worth the benefit and it doesn't even pass the benefit-cost test.
Yes, the Vamo can do it. No, that doesn't mean you should. I have two Vamo's and a boatload of 350 cells. I haven't stacked'em yet and I ain't gonna.
Baditude,
I would add two more items to your list:
1. INSPECT your batteries both before and after charging. Look for distortions (i.e. dents, puffiness) and stains.
2. Carefully feel the batteries both when you start charging and periodically during charging. If they're getting hot, remove them at once!
(In either case, don't use them and dispose of properly)
My recommendation was already in bold print in the previous post. Saved you the trouble of researching. AW 18350 IMR
Baditude said:
Better yet, get some AW 18650 IMR.

I agree with the red AW IMR 18650 batts for all my stuff! I use them for my Provaris and other vv mods. However, if you eventually get into a mechanical mod, then you would wanted protected batts. But with the Vamo, I'd definitely get the red AW IMR batts
Exactly.
And to the person who mentioned riling up the REOnauts: we instruct our newbies who come to us with questions on protocol with a loving, tender hand. And we aren't worried about a tube
