One of mine kind of ruffled up the negative end of a battery a little bit. Not really concerned though.
you might want to try some of this, use very sparingly, i took a small tiny brush thing out of the X-old lady's make up and put a drop on it and i can do several connections, apply it to the top & bottom of your batts, i even put it on my 510 atty and device pins....if it does not get better send it back. in case the link below getts banned its "

Oh ok now I know how to remove batteries without tearing the cover. I made 2 coils out of 26g Ni200 hand twisted with 0.059 and 0.072 ohm. Both turn out fine on M class but both sometimes show short on my IPV4. I wonder what's wrong. But by pressing the IPV4 fire button few times the short disappeared and ok to fire. Hmm...

after you installed the room temp build on the IPV4 did you set your resistance, by pressing the up/down buttons at the same time?
if not what you described happens.
Yeah uncalled for... But that happens when something isn't locked down tight... And internal resistance can make a different

Is a dual 28 nickel build at .085 ok to run? The specs say it can't run under .1 I believe but the mod will fire down to .050 from what I have heard.
So much for someone with over 2000 posts try to help someone with a whole 12. Not sure why he did that response, sando. I didn't see anything wrong with your suggestions.

The only reason I ask is because the spec sheet on the chip says otherwise and I don't want to mess it up or overheat.
does anyone have problem with the ipv4 reading little higher resisting? my ohm meter read 0.15 but the ipv4 read at .3
Ya I did, then mine started to get hot by the USB port slowly until every drag it would burn to the touch. Resistance started a little higher then went out of control, Wait it out and see if it gets worse, if it does. Likely yours is defective if it gets worse
It does fire down to 0.05, there's confusion in the spec sheet - Yihi said something much higher, but then Pioneer4You recommended a range of 0.05Ω to 0.10Ω. It definitely fires to 0.05Ω and says Low Resistance below that.
No I have the opposite problem - Set Resistance usually reads a little lower than my other mods/DMM ohms reader. Like a 0.12 will probably read 0.10Ω, at least when I'm doing Set Resistance. I haven't checked the normal on-screen reading carefully but assume it's the same. This is not uncommon I've heard.
First thing you can do is carefully clean the 510 with alcohol (99% IPA preferably, 70% is OK too). As well as a big bottle I also buy little swabs, that are sold as pre-injection swabs for nurses. Little pads soaked with 70% IPA. I take one of those and then with the head of a screwdriver or tweezers I push it into the 510 and then all around it, rotating it. Often I get a lot of black stuff when I clean a 510 for the first time in a while.
I also have a couple of spare toothbrushes which are great for cleaning threads. I spray a little 99% IPA on the bristles and then scrub round the 510 heads and gently on the pin.
That said a difference of 0.15Ω sounds pretty high, too high for dirt alone in most circumstances. it might be the wiring inside the 510. If you're technical it's very easy to get the cover off and inspect the inside of the 510 - maybe a wire is coming loose or the pin has sunk so that you're not getting a firm connection.
If you're not comfortable doing that, a return is your only option.
The resistance reading is vital for accurate TC and reading 0.15Ω too high will make TC widely inaccurate - like hundreds of degrees out. It should be usable for non-TC Kanthal still.
Here's a couple of photos I took of the inside, around the 510, in case that helps give an idea of what's in there.
