Quick LED question

[locke2121]

I had a auto 510 joy battery die on me...an old clearo leaked into the hole lol. I plan on harvesting the 510 connector from it for my new VV mod...but what about the LED? I don't have a picture, but its a little round board with an LED and what looks like a resistor all hardwired in? how to I test the resistance of this thing? I'd love just to use this instead of buying a new LED...cheap as they are lol. Can a standard 510 LED/resistor setup handle up to 5v of vaping power?

I do have a multi-meter somewhere...just gotta find the instruction book for it lol! I would hate to just hook up a 5V source and see if it can handle the load...just to watch it fizzle..I may use it on something else someday.

Yup.

how to I test the resistance of this thing?

Multimeter set to ohms over the tiny black square with 2 solder points at each end(surface mount resistor). My resistor has 361 printed on it (you might need a magnifying glass- I sure did), which is 360 ohms.

Can a standard 510 LED/resistor setup handle up to 5v of vaping power?

My guess is no. It's pretty much set for not burning out with ~180mah, so you would probably have to unsolder that resistor and solder in a larger value one. Impossible? No. Difficult? You could say that. I would rather solder a regular 120 ohm resistor leading to the little board (. That should keep the current from burning up the LED.

Good luck!
