I considered arcing and I considered them being pushed too hard... Idk... I always made sure my connections were snug but not too tight. Having a touch of OCD and experience in manufacturing/metalworking, a nice fit is naturally important to me lol
Sony VTC4 Pitting? ??

WAAAAAIIIIIT! I just had a thought... maybe it was the charger? My first NiteCore ended up getting dropped down the steps on my way up from underground getting off the trolley so I ordered a new one and picked up a generic little double slotted "smart charger" and maybe that had something to do with these getting ruined?
Mods generally don't heat up because a new authentic Sony battery (or any other known good battery) is bad. There are typically two reasons a mod, or a part of a mod, will heat up.
1) You're drawing too much current from the battery, the battery heats up and the whole mod gets hot because it has a hot battery in it. That can be because you have an old or damaged battery. Most often it's because you're simply drawing too many amps from a good battery. It could also be because you have counterfeit batteries and they are not really 30 amp Sony's.
2) Some part of the mod needs to be cleaned. Basically, a contact surface is dirty and has high resistance which creates heat. Typically it's switch parts that do this and the switch gets hot, not the battery. It can also come from the 510 connection, but most often it's the switch.
The pitting on the bottom of the battery is not from a spring, there is no spring touching the battery. Every time you hit the button there is a small spark when the switch post makes contact with the battery. That spark can pit the battery. The lower the atty resistance the more amps are drawn and the more pitting happens. I've found it takes a lot of pitting to affect the performance of a battery. I sometimes use a bit of 1000 grit sandpaper and give the battery a real gentle rub. You can use a small amount of grease like Noalox on the switch pin to help slow this process down.
Hm, maybe you do have counterfeit Sonys. 1.8 ohms - 2.3 ohms is not even making VTC's break a sweat. Who did you get them from?

LOL, I should know to read a thread all the way to the end before posting! Yup, this might negatively affect the charger and thus your batteries
Check your batteries off the charger. They should be 4.2V, +- 0.05. If they are higher than that, that's bad. You should also not be running the batteries down past 3V regularly.
I try not to let them get too low. There's always a way to tell. Suddenly getting weak hereafter hours of vaping. ...time for a new battery. Im so tempted to try these out again...but I need my face to be there when I wake up...
If I believed a battery was bad, I would recycle it. Safety is always my first concern.
Go with your gut feel Kashief. Batteries are cheap. Your health is worth a lot more than a couple of them
Let us know how it goes.
