Not only has the terminator reappeared, but sparkplugforsmokers.com claims they have a patent pending on it and they are calling it the sparkplug power regulator. I thought that was interesting since I read the thread where Buzzkill posted the schematic for that device a few months ago in the modders forum.
Also interesting, there is a thread (that will get closed soon because it has devolved in to a flame war) in the general forum where someone apparently had a single 16340 go thermal when they put it in a charger that wasn't even plugged in. It sounds like it is an unprotected 16340 sold with the sparkplug v3. The key thing to note is that the batt melted down while not even in a mod.
