Bike Light Flashlight
How do I power a 9 LED flashlight which runs on 3 1.5v aaa batteries with a 7.6v NiMh recharable battery pack?
I have a few cheap LED flashlights that I would like to power with a 7.6 volt R/C car battery pack. I used to power a regular bike light with it, but the bulb was for 7.5 volts. I'd like to go LED for better battery life. All the LED lights use 3 1.5 aaa batteries. Do I need to add anything (resitors, capacitors, etc.), or are they already in there? Any help would be great.
Your 3 batteries add up to 4.5 volts so you may risk damage to the leds, One method would to add a 5 volt regulator
which has 3 tabs--input (where you put the positive lead of the battery, ground, and output which should supply 5 vdc to your leds
