How dangerous is stacking for 6v? prove it.

Not sure if this link will work and the vid I found is of a RC lipo pack exploding but I imagine that the batteries we stack would go up in the same manner(except contained in a tube, like a pipe bomb) and even an event reduced in scale going off inches from someones face... I'm thinking that it would be like a little grenade, forcing pieces off of a mod to go flying like shrapnel, can this be considered proof of the danger's of stacking batteries?

ehhh.....Yes and no. I've seen vids of cylindrical lithiums "exploding". I've had a lipo pack "explode" on the charger. LiPos go up more violently. The OP's question wasn't so much about the effects I think, but of the risk of it happening in the first place. I'm not sure "explosion" is the right word anyway. I's more of a vent, ignite and burn. It's a process that takes some seconds and with cylindrical batteries in a mod, you get additional warning time. If it's in your hand, it will heat up from the venting and allow you time to at least drop it.

It's a bit hyperbolic to compare it to a hand grenade or a pipe bomb though. Those are instantaneous explosions with far more force and energy than any battery you'd likely find stacked in a mod. Unless a mod's casing is exceedingly flimsy, the weak spots will be the connector and switch. Those will fly off and release pressure before the casing splits, let alone fragment or do anything resembling an "explosion", a word that's used too loosely around here, IMO. If it's got decent venting, nothing will fly off but you could still get burned pretty bad if you weren't sentient enough to drop it. Flame can also be released, burning nearby objects.

There are videos of stacked batteries venting in a Silver Bullet. Nothing happened. Nothing flew off. The switch was displaced a few millimeters and it emitted a lot of hot gas. Another member here reports of having stacked batteries "explode" in his Silver Bullet without it being destroyed, albeit it was too hot to touch for an hour.

In a lesser and/or unvented mod, certain pieces can go flying off, but words like "explosion" and "shrapnel" are a bit strong for what is actually likely to happen in the real world, IMO.

None of that argues for stacking batteries. It's almost totally unnecessary nowadays to stack batteries in a mod not designed for it. Even without any spectacular explosion and flying shrapnel, hot gas burns are serious enough not to risk it.

Well in that case then, I face more danger at work every single day then I do from stacking batteries, lol... May just have to try 6v or higher(for duel coil) with my SB if I can find the right batteries, out of curriosity which would be the best to stack? All I can seem to find is 3.7v and I'd rather use 3-3.2v I think.

The Silver Bullet does not even have a vent hole. Pipe bomb if you ask me. Do whatever you feel comfortable with though.

Silver Bullet is actually vented at the switch . But I drilled an extra hole on the bottom , just for good measure . I stack batteries all the time , and in a year and a half , have never had any issues . But do what you think is best for you . If diligent care is taken , I personally see no problem with it . But that's only my opinion .

AW LiFePO4 500 mah 3.2v batteries, supertmanufacturing.com is where I get mine. I have been stacking batts for over a year and those are the best hands down. Mark the batteries in pairs when you get them, never mix an match stacked batteries. Only use chargers designed for 3.2v batteries and check the voltage with a multimeter after each charge. Besides those pointers enjoy, 6v and dual coils is a great vape

Not only is the Silver Bullet vented at the switch, but the switch is designed to give way under heat and pressure, exposing additional venting. Also, the collapsible spring has been demonstrated to be effective in cutting power in a short condition.

A few months ago, when all the hysteria about venting swept through ECF and certain people were clamoring for vents to be cut in their SBs, it was explained how and why there is venting and it works. Altsmoke was under pressure to disfigure the SB with slots and holes and other outrages until the hysteria died down. Fortunately, AFAIK, they decided against it.

IMO, adding holes and slots is more likely to cause a problem than prevent one. As it is, it's resistant to infiltration by liquids and debris that slots and holes invite. There have been several cases of batteries "exploding" in an SB and not once has the connector shot out or the casing been compromised. That is de-facto proof that additional venting is unnecessary.

Well thats all pretty good news and info, the only reason I'm even thinking of getting batteries for stacking is because of all the dcc I have. Just had my first single coil's show up today so I'm gonna give them a try with the kick in my SB and see how they work for me... who know's I might just toss out(give away) the dcc and the idea of stacking after trying the 1.7ohm single's, lol.

Let's cause these batteries to catch on fire right next to this nice wooden trailer.
