Hey, my dad sells lots of different things, and he got me this defective flashlight today. I took it apart to see what was inside. The flashlight had two lights two different places, so it had 2 buttons. One of the lights was 5 LEDs and the other had 21 LEDs. (Good quality i think!). The small circuitboard the 5 LEDs is connected to, also have a small red diode, and an input for the battery(So it can recharge). The small red light lights when the battery is fully charged, and maybe it could be used in a laser? Please help me, it's my first real "project" if this works
How can i find out the LEDs required voltages etc? The battery is "Li-Ion 3.7V 1000mAh" so the LEDs only need that?
Here's some pictures:
This strange black thing was inside, it is very light, and on the back it has some white tape?

Here's the circuitboard with 5 LEDs, the black thing is the input for charge, and the small red diode is on the back/side.
