Which is what I've been wondering since I read the post which mentioned them. Can someone explain under what circumstances a half wrapped battery might be beneficial?*What the heck is MXJO thinking, Half Wrapping batteries?

Its actually a half yellow, half silver colored wrapper.
MXJO cells are rewraps, not good for low builds, and have exaggerated CDR values.
Mooch tested these cells.
Ill repeat: the vape shop employee installed a crappy battery upside down in a customers mod, while hosting a cloud comp.
Bunch of
idiots.
All of them.

Thank you for the explanation of the cells.
As for the rest of it, I can't, and wont argue with you, as I honestly don't know, only the kid in the vape shop knows for sure and I doubt he's going to admit his mistake.
All things bring equal, if it is a straight mech mod how would a reversed battery
cause a short? Wouldn't current current just flow in the opposite direction?
A switch and coil are not polarity sensitive.

If the wrapper is torn, and the cell is upside down, it creates a dead short. Touching the tube wall, and atty connection at the same time closes the circuit.
In the OP's scenario, the issue began as soon as the employee improperly installed the cell.
Know your gear, or dont use it.
Didn't some one mention the battery wasn't half wrapped but two toned and not half wrapped?
There are no actual "half wrapped" cells. They look half wrapped because half the wrap is silver colored.
In the OP scenario the battery wrapper was torn, probably when it was installed improperly.
Thank you for clarifying that, it sure wasn't obvious from the pictures I saw.

Disagrees, while possible that's what happened, many mods (Caravela for example) are designed to blow the bottom cap should a battery explode (which they never should). The idea is that it's better to hurt your hand than your face.
Disagree all you like, I am 100% correct.
Batteries do not vent from the bottom, they vent from the top.
They also swell, and seal off the tube, which is why we have mods exploding from pressure and blowing the atty off...uless they are installed backwards, then they blow out the switch.
@Baditude even started a thread about improperly placed vent holes.
Im guessing you dont have alot of experience with venting cells.
I do.
Actually the tube wall and atty connection are both negatively charged in that scenario, and nothing exciting happens there. It's not until the switch is activated (connecting the positive pole, down through the switch and then to the already-negatively- charged tube wall) that the circuit path is closed and the hard short occurs.
Mech Mods with top venting holes?
"-Sealed metal tubes will probably explode if a battery vents violently
-The battery itself may physically block gas from escaping to the bottom of the mod should it have vent holes in the bottom of the mod
- Small vents at the bottom of the tube are useless, only very large gas vents near the top have a good chance of preventing an explosion
- Building coils lower than 0.2 ohm will raise the amp draw exponentially and this increases risk - the power graph shows a significant change at 0.2 ohms and starts to climb vertically as resistance is reduced further
- Using cheap batteries with ultra low res coils is a certain route to high risk - it needs 30 amp batteries of guaranteed high quality"

Of course if the switch contact is large and the top of the battery wrap/insulator is comprimised them it can short as soon as you hit the switch with an upside down battery.
No need to hit the switch if the wrapper is torn and the cell is installed upside down.
The circuit is closed upon installation.
There are enough facts to deduce what happened if you are knowledgeable.
People have enough issues just grasping electricity.
Now you want them to understand the mechanical connection of an electrical circuit.
Good luck.

All signs are clearly Bottom Vented(battery reversed) Smoke/char on low side of mod.
Op has made 5 post - All in this thread
Op did NOT state condition of Battery
Op did not state whether the RDA is the included design Hybrid or a Pinless Top Add-on RDA
Op Stated the Battery was ejected, but made no mention of RDA breaking away.(Mod has a 1 piece Base and battery MUST exit through Top)
Not really a lot to go on other than 2 facts:
Battery inverted
Dead Short
Battery may have been compromised as Bad Ninja suggest...............or RDA Center pin failure may have occurred. Either Scenario produces an instant dead short.
