I use a K100 with a Patriot rba (not sure model or ohms) with 28 ga wire. I also used the 2000mah kamry 3.7v battery. Well my mod gets very hot to the touch but only near the rba. Is this setup I have here dangerous, is my question.
Welcome to ECF CS90.
The K100 is a great mod. I used it as my main vape tool for almost six months. If the heat you're experiencing is from the RDA, not the battery, you're OK unless you heat up the battery enough to cause it to vent. Just stop chain vaping or get another setup you can use at the same time. Not knowing the ohms of your build is not good. Get a DMM and start measuring the resistance of your builds! If it is the battery that's causing the heat then you're in the battery danger zone and I would recommend you stop using that setup until you figure out how to use it without heating up the battery. Those Kamry batts are not considered very good and can be dangerous.
Additionally, last time I charged my battery on the stock crappy kamry charger, my battery had what looked like dew on the positive side connection.. I'm no genius but I know this is unsafe.. why would this happen? and am I safe using the 2600mah 30amp sony batteries with my current set up? I have heard of many dangers with cloud chasing mechanical mods and just want to do it safe as possible.
Yup, IMO dew on the batts during charging would lead me to look for a better charger and suspect the batteries too. Either way, this has never happened to my batteries. I've used MNKE, VTC3 and VTC4. No idea why this would happen, but I agree it's not safe.
If your other batteries are Sony VTC5, 2600 mAh, from a known good supplier (so they are not counterfeit batts) they are safe to use. They will not vent with flame, so they won't explode.
