Stacking batteries is an inherently dangerous thing to do, but with the right batteries and mod, the risks are minimal. If you want to stack your batteries, you MUST use protected batteries. Also, make sure you mod is properly vented to prevent a high pressure explosion.
There's always a risk, what minimizes it is using the right batteries (protected) in a mod that is well designed and vented...usually a hole or holes at the battery end of the mod. I stack batteries in my mods all the time and have never had an issue.
Man this crap just gets BLOWN out of proportion , your LAPTOP uses stacked and parallel batts in it so does your flashlight , stacking batteries is about as dangerous as making a piece of toast .
Use a protected device that has current limiting and has vent holes , we have been stacking batts for 2 years in 1,000's of devices and have had no problems so far. If it does not have protection built in make sure to use protected batts.

I would agree that it is inherently dangerous . However if you follow some simple rules the danger is very small.
They may be dangerous when operated outside their safe charge limits ( both undercharged and overcharged)
1) do not mix partially charged batteries with fully charged ones.
2) Do not mix old (that have been used for many cycles ) with new.
3) Always use a vented Mod.
Remember that the limiting circuitry itself can fail and can cause the battery to fail.
Also that the battery may fail catastrophically due to an internal failure/short which the protection circuitry will not protect you from.
The risks are however very very small indeed.
use aw brand or a reputable brand and not crappy b grade batteries .you get what you pay for. for those that are cavalier about batteries, there are several posts about vaporites being injured with batteries that went awry. i think we need to all be telling new folks to show batteries great respect. how many times have you seen crazy posts about multiple spacers and rattling batteries? folks drop batteries on the cement and don't give a second thought about it's internal health. same wiith disharging to some crazy low voltage. rant almost over...get a multimeter and do research before just jumping into mods that require the use of such batteries

I've been using stacked LifePO4 Tenergy batts for a longgg time in my mechanical mods, you just have to be smart and not mix old and new batts, make sure that both batts are always charged properly, and use a vented metal mod. I know people who have purposely made LifePO4 batts fail to see the outcome, and they just vented and got very hot, no fires or thunderball explosions! But of course, if you're using a sealed airtight mod with no venting then you're asking for trouble.
I have two 14500 Trustfires in my VV mod, but my next purchase will be LifePo4 batts, since they seem to be safer in high drain applications. The thread below talks about battery safety issues. In a small number of cases, batteries overheat and vent vigorously, sometimes so violently that the case explodes. Mixing fully and partially charged batts can contribute to this, so it's a good idea to read battery voltages with a meter before and after charging. They should read 4.2v or thereabouts after charge.
You wouldn't want one of these going off in your pocket!

Why stack when you can boost
Because boosting converts Current ( that is what you battery stores ) into voltage and is not very efficient .BUCKING the voltage is MUCH more efficient .
I just tried a lavatube yesterday at 4.2 volts with a 18650 3.7 volts battery (and a few puff at 5 volts), it fried my LR 1.5 ohms atomizer (it was old) but I had the chance to take around 15 puffs before, these were the most satisfiying puffs I had in a long time. I don't know what's better, stacking or boosting, but I can sure tell that boosting do works.
It comes down to battery charge time , or how long you can vape on the Mah you have , that is where efficiency comes in , Ya they work .
