OK..I'm not getting all this...when I was a newbie I had a little aga-t2 genny, and I grabbed my atty one day and just cranked it down on my mod without adjusting the firing pin in my mod.....when I cranked the atty down on the mod's firing pin it drove the 510 contact in the atty up into the atty and the firing pin in the mod made contact with the 510 and my mod suddenly got hotter and hotter I quickly unscrewed the mod opened the mod up and the battery wrap had started melting.....it did not explode....how come it didn't explode....why do we have venting in mods if shorting them causes explosions.why are we suddenly seeing this rash of explosions with these sub ohm tanks on hybrids...we've had hybrid adapeters for years and people have been using them with adjustable atty pins for years, so what's going on.
Depends on the nature of the short, I suppose. If it's a small short from say, the positive pin to the negative threading, then there's only a small channel for the current to travel through. Like, if you have the positive and negative touching the positive end of the battery, then you have the shot circulating across those and the top of the battery. There's a bottleneck on the smallest point of contact - the negative. That surface-area of that bottleneck makes it harder for voltage to push current in. There's a limit to how much current the voltage can push through that tiny, singular pathway.
Anybody know what effect this has on resistance? My gut tells me that as the current is flying through this tiny path and heating it up, the resistance starts to go up and it gets harder for the initial current spike to be sustained. That heat has to do something to the structural integrity of the metal. I would assume that a piece of metal that's getting hot enough to fragment and undergo all of these molecular shifts isn't going to carry as much current, as the pathways have become garbled. Current should thus pass through more slowly.
Now, if the insulator failed and the whole pin was making contact with the negative, that's a much larger surface for the current to move across. You now have multiple entry points. The larger the contact surface, the more current you get for your voltage. The current doesn't have to compete for that one-lane road and since the voltage is pushing just as hard as before, more energy is released.
Perhaps with these newer spring-loaded tanks, it could be that the placement/characteristics of insulator and pin assembly has changed in such a way that a failure results in a bigger short. Internally, contact points are bigger. Fatter posts, bigger pins, etc... ...what starts initially as an external short becomes an internal short when the heat melts the insulator and brings the pin in contact with the deck inside and the current shoots right up through that shit.
A hot spring would probably help reduce the likelihood of this happening. I don't see why they can't be designed like mech buttons sometimes are... ...with the hot spring that breaks the circuit when the short comes through and melts it... ...or maybe insulate the spring mechanism with a material that melts like wax after a certain temperature and floods all of the contact points inside the 510.
This has got me thinking... ...maybe it's not hybrids that we should be focusing on. The problem is with the design of the spring-loaded atty. It's unnecessary for most mods. I can think of no reason why a pin on an atty should move at all. It just seems like this could all be prevented if we kept the spring-loaded 510's on the mod. I know those have their pitfalls, but their flaws are all fixable.
Moving contact points, in general, are probably something we need to be moving away from. If there was any standardization for connectors beyond the fucking diameter, all of our mods and atties would probably be a fuckton safer.
I dunno, just some hair-brained pocket change. I'm not basing any of this on anything concrete.
