Will try my best to answer the questions
1. On the charger plug it says input 100-240v 50/60Hz. 0.15A
Output 5.0v. 500mA
2. I had just taken the battery off the charger to use straight away
3. I must admit I have dropped it a few times (who hasn't lol). Only indoors though never on concrete or anything similar
4. No red light. Just struggling as needed to change coil but light was green
5. I can find out the resistance but will have to get back to you on that
6. Only ever run the nautilus bvc 1.8 coil with this battery
7. This particular battery button never sticks. But my other click battery in a different colour does occasionally stick on.
Really helpful answers! Yes, I've dropped my isticks many times, haha. So heres what we know now:
1. You've ruled out an atomizer short since you checked the resistance and its good, not shorted (and like I said, the mod should have protected against that and just shut off anyway).
2. A battery at full charge is at its highest potential for failure, if its going to fail. That's why manufacturers ship at 50% charge per one study I've read.
3. You're charger specs are per the manufacturers requirements. And if the charger had a failure and overcharged your battery, I would expect it your mod/battery to have failed during charging, not after you remove it to use it. So I don't think the charger is the problem.
So that leaves two possibilities, a battery internal failure, or a short in the itaste 1280 device itself (electronics or other such as loose/bare wire, etc) that caused the battery to discharge at a high current, overheat and vent. A battery internal fault could be caused by a manufacturing defect, or damage by dropping. The only way to know for sure the cause is to take the device apart and inspect it for shorts, visually and with an ohmmeter at the battery connections to the circuitry, (with the battery disconnected), check the fire button for a short, etc.
One things for sure, this wasn't user caused failure, you did nothing wrong at all. Even if dropping the mod a short distance caused some internal damage to the thin layers inside and contributed to failure, I consider this a design defect since battery designs have been improved to protect against things such as dropping and external damage. And if you've charged and used your device several times with no issues since dropping, I don't believe that is a likely contributing factor.
Are your other mods safe to vape? I can't answer that, but i wouldn't be afraid to vape them, I have researched and not found but one other failure similar to yours. I will say don't leave them on the charger any longer than needed, and never charge them overnight. Thats the rule I use with my isticks mods - and I have seen reports of failures of the istick 50W mods (I have the 30 and 40 TC, and they have both been great for me). I charge mine on a porcelain sink counter in case something goes wrong, and only until they are charged then unhook them from the charger.
Hey, thanks for taking the time to give more information, you've contributed a lot to the discussions here on vaping safety. Bottom line is be prepared and know that your device and mod can fail, even though you do everything right, though its rare. You did all the right things when it vented!
