Rig Mod Explodes

[crxess]

If the positive battery connection is on the switch and the negative side of the battery (torn wrapper) is touching the side of the mod, the coil is out of the circuit. The only resistance the battery will see would be it's own internal resistance.

Ummmm.......................No. The Battery sees the almost 0.00(Hard Short) of the Dense Metal Resistor(Tube) rather than the higher resistance - Coil
If the Battery only sees its own internal Resistance - that is an OPEN circuit.

One of my Mech's(4Nine) currently has a 13Wrap SS coil running .82ohm coil Running roughly 20 watts avg. and pulling a Whopping 5 amps.

If the positive battery connection is on the switch and the negative side of the battery (torn wrapper) is touching the side of the mod, the coil is out of the circuit. The only resistance the battery will see would be it's own internal resistance. What happens if you are installing a battery in your car, you have the negative post attached and are tightening the positive side with a metal wrench. That wrench slips, you turn it too far, etc., and you touch the inner fender? It sparks and gets hot, it's a direct short. The only resistance seen is the batteries internal resistance, and the little resistance from the wrench. That's a "hard short". It's the same with a mod, but the switch is in contact with the body of the mod, so the body is now positively charged, all the time, touch the negative side of the battery to the body of the mod, it will spark and see a hard short. The coil sees no power and is out of the circuit.

That is what I have said. An upside down battery and torn wrap are the most likely source.
Any thing in contact with with the negative terminal is at the same potential. In the case
of a mod the outer case, terminal and negative side of the switch became positive because
of the wrongly inserted battery. The tear in the wrap provides changes this as it provides
the difference in potential needed for current to flow. The switch has nothing to do with this
if it is open.

In a mech mod, the switch is almost never truly "Open", with a few exceptions. But with bottom switched mods, like the Rig in question. It's "separated" from the battery, by a spring or other means, but it's never "open" as you perceive a normal switch. Push the switch up, it makes the two terminals of the battery meet the load of the coil. But even when it's "open" it's still in contact with the side of the mod. It's just not supposed to be in contact with the battery.

It is open. That's like saying your light switch isn't open because it is connected to the terminals on either side.

People are confusing Open with At Rest. The switch can be either actively Negative or Actively Positive(reversed flow) or Inactively At rest.
If the switch is working properly <no contact with Supply> it is at Rest and considered SAFE. (OFF-Open)

 

[bfisher]

Yes. The switch is open. And the circuit is at rest. Current does not flow.

You are over thinking this, it's not that kind of switch, there are no internal contacts to make or break like the link. It's always in contact with the outer body of the mod, it's just a matter of if its in contact with the battery or not. But it's ALWAYS allowing electron flow though it.

A switch is a mechanism for connecting and disconnecting two nodes in a circuit. Open just means that it is not connected to both nodes at the same time.

The tube is one node (either positive or negative) and the tip of the battery (either positive or negative) is the other node.

Correct, but he's thinking this has contacts in the switch that make and break the connection, in this mod there are no contacts. It's either touching the battery, or it's not. That's the only connection it has to make or break.

This does not mater. Depending on where the switch is installed when open it is only
contacting one or the other terminal of the power supply. When closed it connects one terminal
of the power supply to the load and then to the other terminal of the power supply.
There is no current flowing through the switch when opened,period. It is impossible.
Current would have to find another path either directly through the load or from terminal
to terminal of the power supply. In the first case the circuit is activated, in the later you have
a dead short.

I think the Battery in that RIG Mod was a Rewrapped TrustFire IRC.

Now back to the Debate on what a Switch Is and Isn't.

LOL

Don't worry, the FDA is going to make it ALL BETTER

However, as noted elsewhere in this document, for ENDS hardware or delivery system components or parts, such as batteries, FDA expects that it may be difficult for manufacturers to obtain premarket authorization for such products, given the great extent of possible variations in combinations of hardware components, if all considered and sold separately. Thus, with respect to such apparatus, FDA expects that manufacturers will be most successful where authorization is sought for entire delivery systems, rather than individual components.

That would destroy the active debating of switching mechanisms.

In this instance it does matter. The battery rests on a ledge where the negative post is supposed to be, which is FLAT. If the battery is inverted, the way the mod is setup, and if set up to prevent battery rattle, the switch is set pretty tightly. The nipple of the battery, on the positive side, which sticks out, could be long enough to reach and make contact with the switch.
So we know the contact on the switch is in constant contact with the body of the mod, right?
If the battery is then installed upside down, there is a good chance the positive side of the battery is making contact with the switch, there by positively charging the body of the mod, right? (In fact I just checked this on my Hades clone, the nipple on the 26650 sits deep enough in the delrin to contact the top of the switch without pushing it in.)
Then if there is a problem with the wrap on the battery, the side of the battery is negatively charged, it makes contact with the side of the mod that is positively charged and we now have a dead short. Switch on or off.
This is why most mech mods they tell you to install the battery pos side up, there is always a chance the nipple on the pos side can contact the switch at any time. Any problems with the battery, then it's a dead short and we have big problems on our hands!

All we can do is wait to see what they do, we've been worrying about this for years.

 

[bfisher]

My sentiments exactly.

No. Your making up fairy tales. There is no indication that anything was faulty
in the mod other than the battery was inserted upside down. No broken or loose
parts. That only leaves a torn wrap and a conductive path from the battery straight to the
negative terminal via the case of the mod.
Note that if the battery was inserted correctly a torn wrap would not be an issue
in an otherwise correctly assembled mod as the negative terminal,the case and,
the tear would be at the same potential and no current would flow until the switch
is turned on and fires the coil.

I thought the Mod Wasn't working? And that was the Reason that the guy gave it to the Vape Shop person so they could look at it?

...

Day of a cloud comp, local shop is hosting three comps one of which is a .1 Tube Class. A few hours before the comp is scheduled to begin a customer in the shop asks an employee for help. His mod won't fire.

...

Or are you talking about Another Mod?

As long as we all agree that this is purely speculation, without any real hope of ever being resolved, I think the battle should continue.
