1 W LED on Nokia BL-5C Mobile Battery.

About: I am a straight forward person, with positive attitude in life.

Hi, I am not an electronics expert, I soldered a hard copper wire to 1 watt LED mounted on heat sink to use it as emergency light. Connected it directly to battery (Nokia BL-5C) taken out from my mobile phone, which gives hours of uninterrupted light and later I do charge it putting it back in my mobile.

    It can be used but it will go flat in 2 hours because a 1 watt LED draws 350 Milli Amps. of current.

    this is really a bad idea, LIPo batteries can't be used that way.
