That made me spit what I was drinking!Live feed?
Can you embed that in the base of my cranium and connect it to my rubrospinal thalamic tract?2 months ago I connected a nearly dead unprotected laptop pull 18650 to a XML LED. Still glowing today...

You'll have to ask wimmer about that...I thought over discharging a LiOn cell is dangerous, especially an unprotected one...

On this Thanksgiving I am thankful for: this thread not being about me.
Draining isn't really the danger. Recharging it is.
Being below 2.5v, this battery is done after this experiment. One And Done.
If you Google your battery model number and "spec sheet" you can find the oem spec sheets stating min voltage cutoff. That is the point you should absolutely never dip below. I've seen anywhere from 2 to 2.8, most in the mid to lower half of that.I see that ZL says this on their 18650 lights:
Builtin over-discharging protection (2.7V cutoff)
or:
Built in battery protections with continuously monitored temperature, current, and voltage, plus a (2.7V) low voltage cutoff
If 2.5v is permanently damaged and dangerous from now on, is 2.7v cutting it a bit close?
Considering that you can light a very low Vf LED like an XP-L where you can see the glow in the dark just by using two lemon halves....
