.....Now my question is what happened ? Why did my battery get so hot ? Was it the DID ? Can/Should i use this battery again ?Dump that battery. .5 ohms is almost a direct short, way too low. Some guys on here are using ultra low resistance coils on here (emonty) so he would be good to hit up for what mods\batteries will hold up under that wattage but even those are usually .8 ohms up. Pretty lucky that it didn't vent, that was 8.4 amps and 35 Watts.
I would just toss that battery.

Might want to look at the switch on your mod as well, could have torched it too.
BUt oddly enough my IGO-L at 0.7 ohms is working perfectly :S
Pretty shaky business IMO, still 6 amps and 25 Watts, especially on a Chinese mechanical, I would stay over 1 ohm with that, not worth venting a battery.
Thanks for the input guys....i just want those *clouds* of vapour that's why im making such low res coils....and yes i am using 80%VG and still not satisified
man i would hate for that to happen to any battery. an imr at that. this has never happened to me and i vaped at 0.6 ohm resistance on my aga. i'd say throw that battery away and use another one with caution.
Either you have faulty battery or the spring can't handle the amperage.
Worst case scenario... 4.2 volts @ .5 amps = 8.4 amps & 35.28 watts...
The 2000 mAh AW pictured has a 10 C rating which means that it can handle a 20 amp discharge without issue.
The fact that the plastic was melting at the switch end of the battery is a pretty good indication that it is the spring heating up.
That said, excessive heat can damage a battery... No way of knowing if the spring got hot enough to damage the battery.
In any case you should look into replacing the spring with something with a higher current rating or add a bit more resistance to your coils.

I have to ask, what did the atty measure at after this happened? I suspect a short that caused your battery to fail.
I've always been concerned about people running these super low res coils on mechanical mods and am surprised it's been this long before someone has had a battery fail. I know there are many who would disagree with me but I believe running these batteries right up to their limits is asking for trouble.

1) .5 ohm coil is not the problem. The battery can handle it just fine. It's not a short (or even close enough to a short), it's just low resistance.
2) AW IMR 2000mah is a 5C battery capable of 10 amps.
3) Smoketech telescope has the switch on the ground side of the circuit. Meaning that the entire mod (except for the switch contact) is positively charged when the switch is open.
4) The entire outer shell of a battery is the negative pole.
5) The spring that holds the battery in place is isolated from electrical current....unless the plastic isolator was damaged or removed.
Too many variables to assume what the root cause was, but it was all down hill once the wrapper was damaged. Positively charged mod meets exposed negative pole equals direct short.
Ultimately, toss the battery. Call it a $9 investment towards your health.

If, in fact, it was a .5 ohm coil yes, if it dropped even a tenth of an ohm, or perhaps the meter read a little high, then it'd be drawing over 10 amps and be unsafe. If something shifted then it would be possible to be even lower.
I agree, there are many variables involved here and it's be difficult to say for certain what the cause was without more details.
Maybe you melted an insulator and got a short that way. Maybe the coil was a little lower than you thought. Maybe your wick wasn't oxidized as well as you though. Maybe your were using a magnet to add a nipple to your battery (a horrible idea, safety wise) and it shifted causing a short. Maybe the battery had suffered damage from a fall, causing internal shorts in the battery. This is all speculation on my part but any of these could have caused this.
Bottom line, this battery was pushed past it's limits and should be recycled.
That dent was in therr beofre form me screwing it in too tight but that was a month ago. ALll in all i tossed the battery out , wrapped my self a 0.7 ohmn twisted kanthal wire coil and vaping it right now on the same mod no problems....thanks for the input guys .
