Just purchased 2 Panasonic 3400 mah. Had this set up for a while now. No problems and I trust the professionals. I'm a happy camper
If you like the way your setup is performing don't change because someone on a forum says there's a possibility that your face will get blown off. Most mods these days have ample venting if a short does occur. Just educate yourself and pay attention to your batteries performance. I run a dual coiled igo-w at 0.3 ohms on an El Kapitian mod. I did my research, asked questions at my local vape shop, and payed attention to my batteries performance while vaping, and I my mod has yet to get hot. The only part of my device that does get hot is the top cap of the atomizer which is from the chain vaping and the coils heating up.
