So i have a royal blue cree xp-e2 with a forward voltage of 3.41v. Now at this current time i am running it off of 2 AA's for a total of 3v.
I had originally bought a pack of resistors to work for a 3.7v battery (and a dummy cell so i wasnt running 7.4v) but it turned out that the ENTIRE batch of reistors were bad. At first i thought it was burning them out when i soldered them so i decided to use 2 alligate clamps but still nothing and i went through about 30 of them.
So my question is that if i just run the LED without a resistor on a 3.7v battery what would be the possible consequences? This would be only short bursts for maybe no more than a minute or two. I mean i know that LEDs dont just go POP lol from experience of plugging a strand into a higher current almost double its initial rating.
