Has a single 3.7 unprotected battery ever exploded inside a mod (not stacked) running 3.7..

[SonnyCrack]

Or any single battery for that matter running at 3.7 or under..

I've done a lot of searches here and on other sites and I haven't seen anything.. I'm not asking this so I an continue to use an unprotected battery.. I'd just like to know..

Thanks in advance.

I don't know. [Perhaps other vets do and can comment.] I do know that (even if not) I don't want to be the first.

You should be able to get whatever high-quality, protected batteries you need from the supplier who sold you your mod or from such suppliers as AtmosUSA*, Avid Vaper*, MadVapes, EcigSupply, eCigMods, All-Battery, Battery Junction, or Lighthound.

* BTW, I see that AtmosUSA and Avid Vaper (and eLiquidPlanet of course) now carry the IMR 26650 4000mah battery. Now the challenge is finding a mod that uses it. [The Helix has been out of stock and the ShockWave still is not yet released.]​

I'm unaware of any exploding unprotected battery in mods or in ecigs. The one incident that I am aware of a battery exploding was when someone "recharged" a non-rechargeable CR123 battery and put it in a Chuck mod and it exploded. That had notihing to do with the battery being 'protected' or 'non-protected' and nothing to do with the Chuck, but was user error from lack of knowledge of the type of battery he was using.

The possible problems with non-protected batteries comes from either overcharging or running the charge too low. There's a bit more to it but look it up - but with regards to ecig batts:

1. Overcharge is prevented by having the right charger which has it's own protection for that.
2. Running the charge too low is covered by stopping vaping when you have no more vapor AND is prevented by the ecigs MOSFET - you'll have to look that one up, but one of the functions is to prevent 'undercharge' and typically the led goes out and no further depleting of charge is allowed.

"Protected" batteries have their own protected circuits for the same function - so for example, if for some reason your chargers protection was lost, the batteries own protection would stop the overcharging. Same way with the ecigs 'regulated' models, the MOSFET' most notable on Joye batteries, which also govern the 'underload' voltage.

Even if undercharging occurs - if mods are vented (most are) and ecigs have a 'weak point' - think led end - an occurance is most likely not to be 'contained' - iow, no explosion.

That said - it is highly recommended that you use the 'double protection' of the protected battery.

This is a layman's explanation from reading of those more informed and/or it being their work, and I'm sure there's more info that one could get if needed but it would take more reading that is appropriate here.

A single battery has not exploded, to my knowledge. However what has certainly happened is that a mod, and the battery within, has been found to be red hot and had to be thrown down (happened to one of our staff). So we can say that a cell is not 'safe' just because it is not paired up. It's debatable if it would have exploded since there wasn't another cell behind it, driving it - but I don't think anyone would want to be the first to find out...

So the short answer is: no - 2-cell arrangements look riskier - but 1-cell arrangements have their issues too.

Don't use unprotected Li-ions because they cannot protect themselves from being overcharged. However, if you check every single cell every single time it comes off the charger, you can disregard that.

The MAIN reason Li-ion cells go explosive is by OVER DISCHARGING I.E. too much current draw , this causes the electrolyte to break down causing internal shorts that cause over heating and gassing that causes them to explode .

That is why it is a good idea to have a over current protection device in the Unit or at the minimum a protected battery that has this built into it ( as all do from my research ) .

As far as stacked batteries go there is no evidence I can find to show that they are any more dangerous than a single battery , if you can point me to this evidence please let me know I would like to see if it .

Li-ion batteries need controlled charging as well over voltage in the charging process can result in battery failure as well as charging them too fast ! .
