I ordered 2 16340's, protected, and they wont fire when I stack them. They are both reading at 3.3v's and but wont work when I stack them. I thought you could stack protected batts. Also, what the difference between rcr123 and cr123's. Thanks 
Stacking help :( please

I don't know about the rcr's and cr's,so i'm no help
my 16340's(AW imr16340's,and AW ICR 123's) are 3.7v.if yours are 3.3,they need recharging
if they are 3.0v(like the tenergy rcr123a 750mah)again,sorry,no help.

Indulgence. Does not have a protection circut. When I tested the batts, they singaly read about 3.33 each. When I tested them both together, it gave me .06v's. Tried it over and over again.. Its the batts. (So are protected batts stackable?)
Yes protected batts are stackable and only protected or IMRs should be used in series (stacked) for safety. If I recall cr2 are unprotected batts (old tech) and they definitely shouln't be used in stacked conditions.
The only batts I use these days are AWs, both LI Ion and LiMn (IMRs) They are more expensive but IMO are the best you can buy for consistency, performance and safety.
With protected batts, the PCB prevents a "non-safe" condition e.g using LRs at 6V (draw too much current) not saying that is what is going on here, just saying. Never attempt to move past a safety feature of a battery, it is protecting you
If it prevents a non-safe condition, then why when I test them with the meter, in series, are they not able to connect with eachother. They are being tested outside the mod, just two batts, lines up.. Do these 16340 protected batts will not fire if put together, which I have never heard of. I was wondering if this was true for all protected batts. Yes I agree, AW's are the best, but they arent protected, just safe chemistry.Would you be able to awnser my question if I posted pics of these batts?
From bits and pieces of this conversation, These are Rechargeable not primary cells?
They have a protection circuit on them?
They are button top so they touch each other?
Outside of the mod stack should read the sum of the voltages, inside the mod there could be another "contact" issue.
If they are not protected then they may be 3.2 volt cells. Not the 3.7 volt cells most folks are used to.
Once you get the 6 volts issue solved you will then probably run into overloading these with anything less than a 3 ohm atty/carto.
Here's a link to a place that sells 3 different RCR123A cells. Read the description of each to see what you have.
Then there is the IMR as a 5th type

OK,
In order to troubleshoot effectively we can't go helter skelter all over the place, are we cool with that. In effective troubleshooting we remove part of the equation and see if the results change etc... I am not trying to be condescending here, I am just trying to slow you down IOT help you solve your problem.
So lets forget about protected and unprotected for a second OK?
Tell us exactly what type of batteries you have and... if they are protected or not. The mfr of these batteries is important to some extent, and yes pictures would help.
I have used many batteries in stacked conditions and never had a problem. I always maintain my batts in sets and dispose of the "set" if one becomes faulty etc... It seems from the garbled info provided (sorry) that they seem to work OK (?) individually but do not like playing together, which on preliminary information would indicate a faulty stack regardless of the reason, which as previously discussed the stack is useless as you cannot satisfactorily vape at 3V.
Are you sure you have a positive contact between the batteries e.g are they taped together?
Have you rotated them to see if a different reading gets rendered? Regardless of the result, the stack is useless if you get different readings etc...
This is your starting point, we will go from there
As I recall, we had the exact situation develop with a couple of batteries that had been in a mod when it was dropped. Each cell measured around 3.3 Volts, or so; but, when they were put back in the mod, they simply wouldn't fire the atty. Checking with a meter at the atty connector, when the mod button was depressed, yielded only millivolt meter readings for the series pair.
Were the batteries your having problems with dropped, by any chance?

RCR123 are the designation for Rechargeables, CR123 are the Primary one time use cells.Also, what the difference between rcr123 and cr123's. Thanks
Fully charged Rechargeables will be at least ~3.6V off the charger.
Do note if you are stacking for so-called '6V' vaping the Tenergy 3.2V protected Li-Ions will often trip with a lower ohm load, while the unprotected Tenergy 3.2V Li-PO4's will not.
The same phenomena was noted in the stacked unprotected CR2 days. When the protected version came out a Joye 510 would pull enough current to trip them.
