    I've got an Hcigar Nemesis Clone and although it's not real, it's said to be pretty damn good. But I've been having a problem. For what seems for no reason at all, my battery will start getting real hot. Enough that as you can see in the photos, the insulation has been marred.

    This happens when I either first put the battery in, or adjust the button, top cap or top pin. And it ruins the insulation at the bottom of the battery.

    It doesnt happen a lot. It seems totally random. I'm using aspire bdc tanks / coils, and they don't seem to be very consistent and reliable. I'm switching to a RDA.

    I would like to know how unsafe these batteries are to use, what could happen, and also, WHAT IS CAUSING THIS?

    Thanks.

    I don't know what's causing that to happen, but you should really re-wrap your batteries before using them.

    Those don't look the same as my legit AW batteries - where did you get them?

    I looked it up on AW's thread on another forum - the 2000mah batteries DO have a slightly different wrapper than any of the others, so those are legit.

    I cant re-wrap them, they will not fit into my devise that way.

    No problem. They're also rated for 10amp continuous, so pretty much no matter what coils you're using in your toppers, they'll be fine. I don't know any heads that come below 1.2 ohms, and those 2000mah batteries are safe up to .8

    Do you have a multimeter? Last thing you want is a short and no way to find it.

    Looks like you have a hard short. Perhaps your topper is shorting. Not very safe.

    I do not have a multimeter. My coils are 1.8 but i plan on building my own atomizers. I should not go below .8 with these batteries you say?

    They're rated for 10 amp continuous, and we generally say halve that to be safe. .8 ohm draws 5.25 amps

    Definitely get a multimeter before you continue using your mech - with a short like that, your battery could easily vent on you, not safe at all =\

    Rewrap with Teflon tape - extremely thin stuff. Also very nonconductive and resistant to heat.

    If you don't have a meter how do you know your coils are 1.8 ohm? Or you don't have a hard short for that matter?

    Get a meter. If the condition of those batteries doesn't prove you need one nothing will.

    Properly sized batt should not get noticeably warm.
    Please don't hold your pipe bomb mod near your face or store those abused batts near flammable material.

    the coils say 1.8ohm on them. they're probably pretty close to 1.8ohm i would imagine, but I could be wrong.

    thanks.

    Well you said the problem is happening with multiple toppers, so it ain't the head that's the problem. Your mod must be missing a piece of insulation or something.

    Take your nem apart and take pictures of every piece so we can look over it for you - most importantly the end caps.

    I'd look at upper firing pin and topper 510 connection. Many toppers have a protruding center pin which minimizes hard short chance. Upper firing pin must be centered and insulated from body (not touching top cap).
