don't ask why... it's really hard to explain why (no, not for inside my car). but can i wire up 3/4 LEDs to a single AA or 9volt battery? do i need to do anything different? i want to wire 3/4 green LEDs to a single battery.
please post if you know. |

i used a battery to test mine...just take the positive end of the led and stick it in the positive end of the battery, and negative to negative.

do the math on how much power the led takes away from the battery and find out the capacity of the battery

i used 2 AA batteries per 1 oznium.com LED. for testing purposes of course. but yea, 2:1 ratio is what i used. SINCE the batteries put out 1.5 volts or w/e and my red LED is 3 volt resistant or somethin. i dont know what im sayin but i used 2 AA's and it worked
