i am using toooo much juice

Knowing the consequences of vaping an overloaded mech mod is crucial for anyone trying it. Not knowing the exact resistance and not being able to calculate the load on your battery is asking for trouble. All batteries aren't created equal and the bad ones don't give you any warning when they decide to enter self destruct mode from heat.

Anything below 1 ohm can be dangerous territory. Understand battery safety and know how to use ohm's law. If I were you Brian, I'd buy a regulated mod and vape 1.6 ohm coils on a Kayfun. It's much safer and a really good vape.

What to do? Well, you first need to know what can happen.

Possible reactions are (in order) : heat, venting, flame, outburst. A lot of people have tried shorting the newer generation of LiIon batteries and mostly got heat only. This does not mean the rest cannot happen and it has in some cases.

In a sealed tube, a shorted battery can act as a pipe bomb. Since all mods I've seen to date have vent holes, it is not likely to happen, but I still would not take a chance. Drop it behind a desk, in a metal container, whatever is at hand (BUT... see next line) and hide behind a heavy object or get out FAST.

Older batteries actually caught fire. Battery vent holes seem to help prevent that a great deal, but you never know, so try to throw it near or into the least flammable material or place around.

When a lithium battery catches fire, the fumes are highly toxic. Get the hell out and wait for the fumes to dissipate.

Know that you might only have seconds to react, so act fast. How do you know catastrophy is at hand? 1- Extreme heat 2-A popping sound meand the battery is venting and could release hot material in a burst. 3-If it really goes wrong, then a sealed mod could blow the weakest attachment out like a cannon or the battery could plain catch fire. Again, this is not very likely anymore, but not impossible at all. Most of this happens extremely infrequently, but has happened in a few cases. Any disguised cheapo battery could surprise you, so I'm usually more prudent with recently purchased batteries.

Thank you sir!

Although, I doubt I'll ever get into the more dangerous areas, it is still nice to have the knowledge.

My pleasure. They are very rare events, just like house fires but just the same, it is better to know what the signs are and what to do.

Excellent post The Torch . Just wanted to add a couple of thoughts.

The newer generation of Li-ion batteries that are safer are the IMR and hybrid batteries. The ones that 'vent with flame' are the ICR Li-ion batts. The last are still made and are typically protected by a small circuit board at the negative end, which is why they are a bit longer than non-protected cells. The protection shuts down current flow if there is too much current draw. The problem with that is not all of these boards are of the same quality and all of them can fail. Then there are the unprotected ICR Li-ion batteries that are still made. Those are basically an explosion waiting for an opportunity to happen.

Thank you and great additional info; I forgot to mention protection circuits. One small thing, though: I thought the circuit was at the positive end with sometimes an extra disconnection board on the negative end... I got this just from observing the wrapping as I yet have to kill a battery to take apart.

I've never taken a battery apart either. This is where I got the info on protected batteries: The Anatomy of a Protected LiIon Battery.

You've probably seen the website before. IMO this guy knows a lot about batteries. lygte-info is one of my go-to sites for battery and charger reviews.

Darn, I've seen that site so long ago I forgot all about it. Then again, I can't seem to ever find the time to visit the Battery University site either (which seems to be down right now, so back to vaping and wine )
