Okay firstly I always do 2 10 minute sessions per bowl. I usually start it at smart path 1 and by the last 5-7 minutes of the second 10 minute session I'm at smarty path 4. Somewhere in the middle, I usually hook it up to my bong. I've only ever used the battery it came with. My herb has never combusted. In my honest opinion, I consistently get great results in terms of vapor quality and quantity and the taste is pretty good too. I have not reason to believe there is anything wrong with my unit (if there is I'd like to exchange it for the real deal because if this little thing is supposed to be even better that's amazing). BUT if you don't think this thing can get extreamly hot, you're either running it on very low temps, or you're sessions can't be very long. No, it's not going to burn you (if you have half a brain not to clench it too tightly for more than a few seconds while running on higher temps). Just because it isn't lighting your hand on fire however, doesn't mean the battery isn't reaching dangerous temperatures. I wish I had something to test the heat of the battery with me to get a little more scientific with it. At this point however, I would be extreamly cautious and concerned until we as a community ,and hopefully Da Vinci as well, can adress this issue. I'll try and get something to test the heat out today and see what happens.
On a side note: For those of you who are curious about vent holes, I believe air travels up through the bottle of the vape (on the bowls side) through the hinge area.
Thirdly, most vapes have an auto shutoff timer, but that doesn't mean it was designed to ONLY allow for a single 10 minute session. If that is truly the case with this device then someone let me know if they want to buy this thing cause that's just not me. I actually usually do a bowl through the mighty. Then hit my IQ for a 20 minute sesh. And then finish off with another bowl out my mighty. Point being 1 10 minute sesh for me is like taking a drag out of a cigarette and then having to put it out. Da Vinci did comment however that they may look into allowing us to customize our smarthpaths for longer than 10 minutes and remarked that that longer sessions are more up their alley than everyone being so focused on micro dosing and short sessions.
Also, keeping in mind that I am by no means an expert on batteries, so can someone enlighten me. If the temp ends up being an issue, are their batteries compatible with the IQ that simply have a higher temperature threshold for venting?
Lastly, and most importantly what are the proper safety precautions to take if a battery does end up venting on me?
Edit: For those of you saying your device NEVER gets too hot to hold, can you please leave a comment as to what temps you are running on, how long your sessions are, and what you mean by it isn't too hot to hold. Like someone mentioned previously (even though they were somehow using this as a point to defend the fact it doesn't get too hot) I find myself having to hold the device by the hinges on the mouthpiece side being that it's the only place not hot enough to be uncomfortable when held for more than a few seconds.
The fact the mouthpiece doesn't get too hot is a godsend after owning a Cera however. That thing would start to burn your lips after a few minutes.
