RX300 caught fire!!

[VaperZen]

Hi All,
I was using my RX300 as normal and all of the sudden it caught fire in the battery chamber, I actually saw flames. The Sony VTC5A batteries were from IMR batteries and only a couple of months old so I know they were good ones. I was using only 70 watts on a .17 coil. I ran it outside and put it on my porch, after one hour, I checked it and it smelled awful but there was not a single mark on any of the batteries! The RX300 was only 4 months old. Of course I threw ALL of the parts away, I just can't figure out what happened or if this has happened to anyone else. Has this happened to anyone else?!
Please be careful if you buy this mod! Mine had some kind of glitch.

Thank you,
VaperZen

My guess is the heat weakened the solder on a wire, it came loose and created an internal short inside the mod. Either that or one of the electronic components on the board had a catastrophic failure. Only disassembly will show you what happened. The batteries may not even be compromised, but throwing them away is the safest bet.

Thank you very much for your time and help Scott P.!

Scott P,

I looked in the battery chamber and I didn't see any lose wires, though it could have been one on the inside. Thanks for the advice!

Sorry to hear about it. Is the mod still under warranty? As yes, it sounds like an electrical issue of some kind. Ditching the batteries is probably the safest bet too, unfortunately.

Take the mod apart and see whats going on, unless you are warranty claiming it, then of course don't. If you do take it apart, take pics of everything. It may just be a one off thing, mass made stuff isn't perfect but the more info that can be archived the better, is the way I see it.

I'm leaning towards the board/chip failure side, if it was a battery, one would generally see more evidence. I imagine, since you saw a flame, there a least be soot on a battery(s) or wrapper tears from swelling.

You did good though, getting it outside and not trying to reuse components. I had a battery short one time, that really brings on a craving for a smoke, lol.

I had a similar bit of excitement with a Sigelei 20. I just got smoke and heat though not flames. I took it completely apart and couldn't see anything wrong. My guess was a chip failure.

I did retry it with a new battery in case it was just a bad battery, and the same thing happened. So I killed 2 batteries instead of 1.

If it is a component failure it will be on the actual circuit board. If it was a solder joint failure on a wire it would most likely be one of the wires that connect to the 510 pin on the inside. I doubt you would be able to see either one just looking into the battery compartment.

actually taking the batteries to a recycling center is the safest way. never throw away batteries. most best buys have a recycle bin by the front door

I hope most of us know that's a given.

all electronics works on smoke.once it stops smoking it will not work.

am I the only one who's surprised all of them haven't caught on fire?

This would be true. Here the Garbage company provides buildings with bucket containers for batteries and they pick them up with recycling.

Not sure if the garbage company isn't also creating a hazard with that though. All sorts of batteries, lithium, etc. just end up dumped in a large bucket with a hole in the top as that is the container they provide. They also recommend that residents in single homes just dump them all together in a plastic bag and stick on top of landfill pick up bin. Is this really safe disposal?

This there website on how to dispose of hazardous waste and the picture is what they expect.

Well, mine didn't. I used my Wismec RX200 (a gift) for nearly a year (now retired as a backup). It had been my all day mod until it developed 510 center pin issues (a common complaint with this model).

I wasn't particularly impressed with the circuit board because I was only getting a day's use with 3 LG HG2 or 3 Samsung 30Q batteries, and I only vape 30-40 watts with a 0.5 ohm coil. I kinda got tired using a 3 battery mod and only getting a day's use out of it with a set of batteries.

Pretty lousy energy management. In comparison, a get a full day's use with a single Samsung 30Q in my JAC Vapour DNA75 vaping the same wattage and resistance. Gotta love DNA mods; they are more expensive but worth it in the long run.

nice! at least they do that. most places dont

Pics or it didn’t happen.

Btw, I detest Wismec so I wouldn’t be surprised at all if this happened.

 

[Robino1]

Thank you for the warning.

I'm glad that nothing was seriously damaged other than the mod.

Why? Did I miss all posts of Wismec mods overheating? Seems like this place has had mostly Smok mod problems.
I'm not seeing anything, I guess we travel different roads here.

I used a VaporFlask Lite (designed by VapeForward and built by Wismec) for years and now my wife is using it. Never had any issues.

Don't get too upset...it was pretty much a blanket statement regarding ANY device that runs 300w. I have no Wismec products or SMOK products to judge anything by...but 300w is pretty scary.
