So, an update about the vape, everyone!
when I cut the bottom of the pen, using a saw periodically so I didn't heat it up, at the very end of the mod, literally bubblewrap came out. not kidding. I said ok, let's check the battery, and it was a lithium polymer that was 30 mms tall and had a diameter of 10 mms. I thought there would have been a nice actual battery inside, but I got a battery that was 3 cms tall.
That is not even the main issue, the coil connector has a middle pin, which is the anode, and the case is BAT cathode. Ok, so smok used the whole case as a wire, nice design ok ok. But after a little reverse engineering, I found out that the negative connection is made off of a loose connection, which is literally the outside metal casing of the micro USB connector, barely touching the case. No wonder why it sometimes smelled like electricity arcs inside when I vaped while biking, it was because the bike shaked the vape and caused arcs to appear.
so, this is a 20 dollar vape. It served me well for... well, a week? I am going to save up some money and get a real vape!
Thanks for the advices, everyone, you are perfect people!
