Batts fusing

[ianmark2012]

i have a smok gpriv 2. Ive noticed that the batteries are quite tight to put in and so get scruffy looking quickly. The wraps on the top of the batts rip and show the battery. After a week or 2 i end up getting smoke from a battery or 2 and need to bin themas they get very hot so assume that they are fused/about to blow. Is thos normal or am i overreacting. Stopped using my gpriv n gone bk to the gx350 for now. Thanks. Hope i make sense.

DONT USE THOSE BATTERIES WITH THE CELL EXPOSED AT THE TOP

its definitely not fused, that would be the start of the battery venting gases and maybe the the internals of the mod failing , battery safety should be the number 1 priority , always keep your wraps in perfect condition and re wrap when necessary, also buy your batteries from trusted sources, like fogstar and make sure you ar using the right batteries

Far from overreacting you are under reacting.
You should not use any battery with a ripped wrap.
Wraps are cheap and easy to replace, Watch a couple of youtube videos on rewraping and buy some wraps.

You've done the right thing but it sounds strange they are that tight.
Where did you buy the batteries.
Can you post a picture of them for others to see.
I've got around 20 paired of either 25R or 30Q and none are that tight except in my smok X cube ultra which is a very tight fit.

Doh!. Was thinking yours was a bottom fed battery door. Could well be a smok thing.

Thanks all. Ive had 1 battery starting to smokecwhen i put it in my gpriv 2. So i ejected it straight away. Then it got very hot so binned it. I use vct6 3000mah batts. They are bout 9 months old so due for replacement.

At the positive end of the battery, there is a thin insulator under the wrap.

That is there to prevent short circuits.

Even though only the centre of each end of the battery is where contact should be made - positive at one end and negative at the other, the WHOLE outer surface of the battery is negative - the base, all the way up the sides, and the top edge. That is what the wrap is there for, to insulate that whole surface.

Up at the positive end the central raised terminal is positive, whilst the edge of the battery is negative, and the only protection there is the little insulating disc with the hole in the middle, which is held on by the battery wrap.

If that insulator is damaged, then as you slide the battery into your mod the positive connector in the mod can end up touching the negative edge and the positive terminal on the battery at the same time.

If that happens, you are hard shorting the battery which damages it internally, causing it to heat up, vent, and possibly explode.

If the mod has a sharp edge on its battery connector that might cause this.

You need to stop this from happening, as it is an accident waiting to happen.

It's even worse than that in a series mod (which I presume this is) because one of the cells will have the whole outer surface as positive.

Time for the bin sadly. Terrifying stuff.

Safely dispose of the batteries, ie not in the general waste and dispose of the mod too. Never ever use batteries with torn or nicked wraps [emoji852]
