Battery Wrap

At what point does a peeling 18650 battery wrap become unsafe? Some of mine are starting to peel back where it wraps at the base. Thanks!  

One of my 18650 batteries had a snag so I did my first re-wrap. I thought I had it positioned well before turning on the hair dryer but seems I got way more wrap on the pos end than on the neg end of that Samsung 30-Q. Here it is next to an original wrap. There's not much wrap at all on the negative end. Do you think it's ok or should do over?

 

My charger has those eeh springy slides to keep batteries tightly set.
Couldn't find a respectable charger without them.

How do you avoid damaging the battery wrap when inserting/removing in a charger?

Inserting a battery is easier as you can preload the slide with a finger.
But when removing a battery the spring slide eats into the battery wrap on the way up.
Would be nice to avoid any wrap damage.

Maybe put a rubber band / twine / other (non-conductive) underneath so it can be pulled and open the spring slide after charging?
Like a slingshot
Other ideas?

I just bought 2 18650 Batteries today. I realized that on one of them, there is a small scratch. Is it still safe to use?  

A few days ago I noticed a new co-worker of mine was a vaper. He had some kind of old, ratty looking mech with some kind of tank I'm unfamiliar with on top. This guy doesn't strike me as the type of person who would be responsible with a mechanical, but trying not to be judgmental, I kept quiet. So yesterday a friend of mine says "look at that guy, what's he doing?" I look over and see this guy dancing around, frantically pulling everything out of his pocket. Out comes an 18650 battery, with a key WELDED to the end of it, still throwing arcs! By this time, his pants were actually SMOKING!!! We go over there to investigate, and he had put a fully charged battery without any kind of case or covering in his pocket with a bunch of change and his keys. The old ratty battery no longer even had the plastic shrink wrap sleeve on it, just a silver cylinder. When it was cool enough to touch, we examined it, and the positive terminal had completely burned away, and it had burned a hole in his pocket about the size of a half-dollar. After lecturing him about using a battery case, we asked to see the battery in his mod. He pulled it out and it was in worse shape than the one that shorted out in his pocked. No insulated wrap, big gouges in the side, burnt spots on the positive end. All we could do was warn him to get new batteries and go about our business. I have a feeling our warnings fell on deaf ears. I even showed him my little $0.99 battery case. I can understand someone not being completely knowledgeable about all the technical stuff, but isn't this just common sense? Sigh.  

Hey guys. I have been in the vaping scene for a little while now. Just curious to what everyone likes to sub-ohm with.

My favorites so far.

Mutation X V3- 24 gauge dual parallel 5/6 wrap
Mutation X V4- 20 gauge dual 5/6 wrap or dual 6/7 wrap
Turbo RDA- both of the above builds work well

I've had the dark horse, doge and doge v2, freakshow, and a few other RDA's and the 3 above have been my favorite....v3 was my favorite for a while until I tried the v4, its now my favorite, and its a tie between the v3 and turbo for 2nd and 3rd place.  

How hard is it to remove the wrap from a mod?

And when you remove it, is there a bunch of glue/residue left behind that you have to remove?

I'm thinking about buying a wrap for a mod for the first time ever, but I don't want it to ruin the mod should I want to remove it later.  

Hello All,

Does anyone know which 18650 battery would last the longest when vaping at 13 watts? I have listed some below but any not listed recommendations are welcome as well.
(PS please don't respond with battery safety information or suggestions for me to look at mooch ratings)
Also, does anyone know if the vendors in the last 3 below links are reliable?

Thanks!

My buddy wanted me to show him how to wrap up some coils. Hes using a vamo v5 and he bought an orchid v3. He doesnt like harsh draws but rather a smooth, light, cool pull. So i decided to try that standard wire that comes in the orchid v3's package. Its that stock, hair thin wire that comes in the box with most of your typical RDA's RTA's, but i cant figure out the gauge dimension on it. Im trying to get him a whole roll of it so he can wrap his own. If you guys can help me out i would appreciate it. Thanks!
