Safe?: 1.5ohm dual coil cartos at 6v using stacked batteries

[bah-num]

I asked this in the battery problem forum, but haven't gotten a reply in over a week and someone suggested I ask it here instead.

I'm using a GGTS and a stacked pair of Tenergy LifePO4 3.0v RCR123A batteries (the green variety). For quite a while I was using these with the Smoktech 1.5ohm dual coil cartos (2 3.0ohm coils, from what I understand). Then I was reading the various battery safety threads and got a bit paranoid that this wasn't a safe combo. The whole "C rating" thing is a bit confusing to me. The problem is I love this combo! The vapor is so warm and satisfying and I don't have to take 6+ second pulls on my PV (the only thing I hate about PV's... the length of the draw).

In the meantime, I've been using the 2.0ohm dual coils, but this isn't ideal for me. I'll stick to them if it's not safe to go back to the 1.5ohm... but I won't like it very much

Am I just being paranoid or is using a 1.5ohm dual coil carto at 6v using stacked LifePO4 RCR123A batteries not a safe combination that might lead to a battery failure?

Thanks!

Other vets more involved with PV electronics can disagree with me (please do I am wrong here), but...

I personally think this is very risky, not just to batteries, but the activating switch (what you press), and other electronics inside. With 6V and a 1.5 ohm carto, you are drawing 4 Amps from the batteries, and 24 Watts of power. These numbers are WAY high!! Many here think 12 Watts is too high for the batteries or electronics, so 24 W is really over the top. You may like it, but your GGTS probably does not, and the switch will possibly die quickly, if the batteries do not fail. Realize also that battery failure (venting) can be extremely dangerous, and could cause a fire that cannot be extinguished easily. Many "fat batt" batteries, like the Echo, have safety shutoffs when the drawn amps are too high, for the same reasons. Even my beefy external power source for my 5V passthrough is not rated for more than a 2.5 Amp draw.

I would strongly advise against this combo. I don't think the risk to the GGTS electronics or yourself are worth it, and you could be literally be playing with fire.

Another issue to consider is that if there was a fire, and the fire department was called, the media would be more than happy to jump on it and attack vaping. This is what happened when a guy had a 2xCR123 stacked mod that exploded. He was seriously injured, and news outlets had a field day. But you can always contact the vendor that sold the GGTS to you to get a second opinion. If it was from COV, Bruce would probably know a lot more about the internal ratings and the ability of those batteries to withstand such a massive current draw.

Until then, I would advise backing off quite a bit on the wattage/amperage. Good luck!

Internal comment...
If I am off-base here, I would be happy to delete this, but it sounds dangerous to me.

I'm going to agree with Kurt here.

When I first got my SB, I ordered a set of the same batteries that you describe, and a box of 3.2ohm cartos. I used them for a day or two, all the while reading the forum for information on stacking batteries. What I learned was, though explosions/venting is a bit unlikely if properly handled, the odds of having a melt-down in your hand was significantly higher with stacked batteries than a single cell.

As far as I'm concerned, I'd prefer my risk of breaking my PV to be as low as possible. The ones that can be used in this fashion aren't exactly cheap, and some of them aren't that easy to get your hands on. I'd rather not have to replace something that I broke because I was misusing it, or handling it improperly.

For now, I'm using a Kick, and the LifePO cells are stashed in my hardware box.
