Seeing More Newbies going sub-ohm... Scary stuff.

[EddardinWinter]

No. Yours should have said..."sorry for posting that false information in a thread about safety"

I have no problem ever admitting when I'm wrong.

I am sorry I re-posted a chart from P. Busardo's site that was flawed. I have also sent Busardo a message about the issues in his chart, hoping he will remove it. Of course, I did only post that in response to some numskull posting something in a battery safety thread for other vapers that implied we could ignore CDR ratings since we only pulse when we vape.

Let's review, shall we?

First, I said:

21 amps is exceptionally dangerous if the battery's CDR is 10. I view the AW IMR as a gold standard battery with regards to safety (safe battery chemistry, good QC, performs like the manufacturer's ratings say it will)-when it is used properly. An AW 18650 IMR has a CDR of 10, if it is used in an application where its current demand was 21 amps for continuous use, it will likely fail and vent. Should the emergency vent be located at the end of the cap for the tube mod. expansion could well prevent the vent from functioning. In that case, where the pressure has no viable vent, you have an real explosion hazard.

And you were inspired to post this (as a response to my post):

Good thing vapers don't continuously discharge. Vapers pulse, which is defined as 30 second bursts.

I await your Mia Culpa.

going to tasteyourjuice and see if new charts exist.

This reminds me of this topic, were the TS is even a minor.

I don't mind him doing it, but it's this kind of ignorance that causes us e-cigg users to look bad.
To many doesn't know the safety precautions needed.
(This guy seems to know about it though, but this is my general view of youngsters that are going into e-cigg. They jump straight onto mods.)

Is the pulse duration that's tolerable on a vaping battery listed? Electronically, when I build things, acceptable battery pulse durations are defined as 500 ms or below, or way too short for a good vape. Electronic bits and pieces can have maximum pulse durations of 10 ns, but that wouldn't be a factor at all in a mechanical mod.

I don't, per se, mind somebody jumping to an electronic mod as their first e-cig if that's what they want. Really, they're just big eGo batteries with VV...so kind of like an oversized, steroid-infused eGo Twist.

I've been taken to task for my emphasis on battery and device safety. I always recommend at least a 100% margin of safety (so don't draw more than 15 A from a battery rated 30 A). The reason I recommend that is I'm aware how loose manufacturing tolerances can be in some cases, and you can never tell if the battery was dropped, heated, or otherwise taunted after manufacture but before delivery to your doorstep.

Besides, this thing is at your face. And too near my expensive teeth for comfort. I can't afford $50K in implants.

Yea i agree with you. As long as they take the precautions that's needed.
I mean, i'm still quite new to all this. But i've been doing tons and tons fo research first. Just to ensure i don't f*c myself of
There's a case where i adviced a guy to take precautions and read about batteries but he refused to listen. He went straight into sub ohm. How it all went out i don't know. He was like "i like risks" ... uhm whatever floats your boat.

Whereas my watchwords (and from the sound of it, yours) are "don't take risks." At least not when placing a battery near my mouth.

Certainly one can do unsafe things even with an electronic mod (like putting a low-drain unprotected ICR in there and expecting everything to be peaches and cream). But at least it's a little harder to hurt yourself than it is sub-ohming on a mech where overdrawing even a good IMR is entirely possible.

I do get antsy when somebody says, "I'm new to vaping and just built an 0.2 Ω coil! Can anybody tell me the power level I'm using!" There's at least three things wrong in that statement...

 

[MorbidToaster]

I've been vaping about 2 months. I basically jumped in head first. I was sub ohming after week 3.

This was after tons of research. I found the right batteries (I own 4 VTC4s and have some VTC5s on the way), a well vented mech (THATS IMPORTANT), and a dripper with fairly large air holes (Trident v1).

I generally have found .5 is the sweet spot for me. I'm really paranoid about safety all the time, but after all the the research I'm also confident.

I don't believe shops should be selling anyone anyone sub ohm rigs though. Wrap it safely at 1 and tell them to sub ohm at their own risk.

MIT defines a "pulse" as 30 seconds per their battery safety lit.

Just like with any hobby that deals with electricity, not researching enough can result in bad bad things happen.

I mean, if one looks at this forum about couple hours before going sub-ohm, one would notice that there are precautions to be taken.

It's up to the individual to notice, in my opinion.

 

[Bunnykiller]

That's cool for your application Bunnykiller, but my PV's power supply (Sony 18650VTC4) will not even be breathing hard with a 0.499 ohm load. At 0.2 ohms it may start noticing it, but it still won't be breaking a sweat.

The power supply does not know what the resistance is. The safety issue is where are we in terms of over drawing the power supply. I think someone already pointed out something like this.

heres a test to see if your application can handle it... put in a .2 ohm load and hold down the button till the voltage on the battery is at 3.1 V. then report back and let me know what gave out first

Uber strawman. You should be proud.

Why would one post this on a pubic forum

Whoever reading do not EVER do what is in quotes...
