Wizard, is that your video, or one you found (maybe a little biased?).
I think there may be something wrong with the mod that was used to demo the 18650 cell.
I've made a "couple" of 18650 mods and get much different results.
The results seem to be different that most test results on 18650 mods posted many many times.
I usually stop vaping at about 3.5 volts (loaded) on an 18650 mod and put it back on charge.
Here's a few shots with a crappy Ultrafire 18650 Big Red cell and it's no where as good as an AW High Drain cell. (note that the second photo is 50 vapes after full charge)
The last is with a Sanyo 2600mah 18650. All voltages indicated are "Loaded".
Late Edit:
I went and checked out the source of the video. So, let me clarify the point I'm trying to make.
The 1000 and 1100mah eGo clones (that don't have a PWM regulator like the eGo) will hit hotter than a real eGo. No questions, hands down harder hit than an eGo. I've used them, just not from that vendor.
The 18650 results posted in the referenced youtube video do not represent the normal 18650 mod.
At least not one that is working properly. The vendor has a nice product. No need to post false info.
If you see it on youtube, it must be true
