Some great info here. Thanks Bad for the links. I like my PT2's and iclear 30's, but will be getting some IBTanks now to try out. Gotta be sure and get that "tank tool" also.

Ugh, for some reason the I always end up at the conclusion that I should get the Provari!
The reason stacking a battery is not good is because too often battiries don't degrade at the same rate. If you get a quickly degrading battery mixed with one that isn't degrading at the same rate, the better battery will try to push the weaker one to equalize them both. This over works the better battery as it is working all the time instead of just when you push the button. This causes the better battery to heat up. Once it heats to a certin point it goes into "runaway". Think of lighting a large spot of gas. Once it starts it generates it's own heat to keep going until the fuel runs out.
Now when a single battery degrades it just dies and you get another one.
Can two 18350s be used in a Vamo? Sure they can! Should they? That's something you need to deside on. Personally, I won't use stacked batteries in mine.

Oh, in case you haven't heard, the 510 connection on the Vamo (at least mine) is less than perfect. I've always been very careful to only just snug my tanks, carts, clearamizers, etc. so as not to strip the Vamo's threads. Mine is a little crooked too. It is however, a $38 device. Pretty cool though. I like mine. I have a couple of these.....
Tank Air Flow Controller
.....coming in the mail this week that should give me some comfort vis-à-vis protecting the connection.

I got the SS Vamo 3 first. Then a K200. Then a Provari. Then an Innokin iclear 134. Also a couple mechs, but I don't really care for them that much. Now I'm just taking a break and doing a lot of nice vaping! The nice thing about getting the Vamo first, is it's so much more than ego c's, you'll be amazed and have fun with it. Then, when you do get a Provari, you'll be amazed all over again. IMO, each device has it's place. One can't have enough, can one? One of everthing please! lol.

Well Larry I've made up my mind and I want the best. I'm getting the Provari. I don't like tinkering around with things and having to keep purchasing mods until I finally get the best. I'm just going for the Provari. I'll make the purchase tomorrow and then get tanks and stuff as time goes by.
Get carto tank, I prefer boge 1.7 ohm coils. I get dry burns from the protank or any wicked system on my VV PV
Try not to place too much emphasis on the smog and power enthusiasts. These are the equivalent of the road and track jockeys in vaping. I recommended a pair of variables [vMax] because...there are so many incredible options available to vapers these days. The VAMO is a good choice based on cost.
Example, I was skeptical of carto tanks. I didn't think they would produce like a tank or a drip. I took my time to work with them on the variables testing carto's with different resistances and different manufacturers. I made amazing discoveries. Boge's have a slight metallic taste. But at certain temparatures it complements and accents the cooler crisper side of Tribeca, one of my top three flavors. The Kanger horizontal bottom-coil carto's bring out all the warmer tones in it.
I gradually found that carto's worked best on mech mods once you found the sweet spot for the device and flavor. Sometimes it's right in the middle of your preferred battery range. Sometimes it's more critical and you save money with a cheap mech and a kick to keep it where you want it. It's worked out like that for me with my favorite flavors pretty much locked in to a specific carto/temperature/power on a fixed mod, with or without a kick. Now slowly replacing those clones that worked best with their authentic counterparts. But it has been a pleasure in the discovery.
Once you refine the art of improving airflow through the punches by tipping cargo tanks during your draw you'll find that slow lung inhales add tremendous nuance to both flavor and vapor production. Carto tanks can blow you away.
You can't rush a good thing.
Good luck!

Stacking batteries is discouraged because while it can be safely done in the Vamo, the steps that must be taken to do it are extensive and the penalty for breaking the rules can be disastrous. Please understand that it increases the risk factor so adherence to a strict protocol is absolutely necessary.
To do it, you have to make absolutely sure that both batteries are brand new and of the highest quality possible. Both must be from the same maker.
Both batteries must have identical nominal and nearly identical actual capacities. Just because they both have 700mAh on the label doesn't mean that they both have actual capacities of 700mAh. There are variations in the manufacturing process and the batteries could have significant differences between them, even if from the same manufacturer. That's why AW IMR's are so highly recommended. They perform as closely to spec as can be.
The batteries must be married and never be separated, until death do them part. They have to be labeled and one of the two can never be used without the other, nor can either ever be used in conjunction with another that is not from the same married pair.
They have to go on the charger at the same time and come off at the same time. They have to be rested for an equal amount of time and have to be tested with a multimeter once they've rested.
They have to be rotated in position. Battery A goes in first one time. Battery B goes in first the next time.
Forever and ever, Amen.
Even though the Vamo has the protection circuitry that the other mods don't, that doesn't mean something can't go wrong. That's where the safer chemistry of the IMR cell comes into play.
The dual 18350 capability is a small advantage that the Vamo has over other systems. The Vamo detects the higher voltage and adjusts how it manages power accordingly. The device will display "Low V" in stacked mode when the tested voltage falls below 6.4v. The only advantage you gain is the theoretical abililty to run at higher loads for longer times, but at the expense of battery life. Real testing of the Vamo indicates that those theoretical gains aren't possible at the higher end of the scale because of the amperage limitation of the device (5.0a). The "safety ceiling" of the device's circuitry doesn't allow the computed power output to be obtained from the higher voltages available in stacked mode.
Example: Assuming a 2.0 ohm coil and max current output, 2.0 ohms x 5.0 amps = 10.0 volts, which is well above the voltage limitations of the device. The power output would be 5.0 amps x 10.0 volts, or 50 watts. Again, well above the threshold of the device and not achievable.
Other mods are not designed for stacking batteries at all, and doing so voids the warranty. Most regulated mods cut off when battery voltage drops below 3.2v. That is 1.6v per battery, which is well below the lowest discharge voltage of the lithium ion chemistry and it will either kill the cells or cause an unfortunate incident. Just because the Vamo can do it doesn't mean that you should try it with other devices that look like they'll take it.
Unregulated mechanical mods can achieve the theoretical limits, but doing so will put such a drain on the batteries that an unfortunate incident is a near certainty sooner or later.
You can stack'em if you want, but unless you're OCD enough to keep up with all of this, it's best to just stick an high quality IMR or hybrid chemistry 18650 in there and let it ride.
I have two Vamos. I've never stacked 18350's in either of them and I don't recommend it. Just too big of a hassle, not enough benefit for the increased risk and it's not cost effective because even the best 18650 cell costs less than two 18350's. It's just not worth it, even though it is possible.
