You should find out good sir...lol, comment count rises again...
I am soooooo hurt people and my ego is deflating at this very moment!!!!! I do indeed consider myself a veteran and will rise to the ranks, deflated ego or not....comment count goes up again!!!
Efest "engineering"
Take from it what you will.
Be safe

Aren't these the ones they had originally installed in the Boeing 787s ?
Holy crap!
ENOUGH!!!

Some end notes:
- Sub-ohming isn't dangerous unless you make a mistake, including but not limited to very poor judgement.
- There are very few reported incidents involving single-battery rigs, but we had dozens of incidents of mechmods exploding or rocketing in the days of 2-cell rigs and Li-ion cells.
- It's likely that modern technology batteries won't go into thermal runaway unless they are repeatedly abused and then hard-shorted, which includes running a load so low in resistance that it qualifies as a short. Even then, quality cells will just melt, without any significant outgas.
- Running any battery in a manner that causes it to get warm (and especially if it gets hot) is damaging it. A rechargeable cell is not made to get very warm, this will cause internal degradation.
So to get a nasty incident will probably need you to:
- have tried to save money on batteries by choosing a cheap one over a high-quality one
- buy a badly-designed APV with no real gas vent capability (it needs substantial vents at the top end, not a couple of pinholes at the bottom end)
- repeatedly heat up the battery by applying a low-resistance load for too long or too often for the battery/load combination, and ignoring the hot battery
- go for broke by machine-gunning a cheap battery already overheated several times before, on a super-low-ohm load, in a semi-sealed metal tube, while ignoring welder's hand
It looks as if "35 amp" modern technology batteries (that are maybe 20 amp cells in reality) are OK though, even when severely abused - otherwise there would be a lot more incidents.
Maybe some of these cells are counterfeit, or some faulty ones get through inspection. Not many, luckily.
We tried suggesting that devices are correctly designed in the first place but it didn't work out, not enough products have real gas vents. Very few people making these things are engineers with design experience, they just have a hobby lathe in the garage and then get the result bulk manufactured. If it works, contract out the manufacture and flog 'em while the going is good. Nobody cares about safety anyway, there are no rules or standards.
