Re: Custom LED Circuit - Wire Gauge?
Larry,
If I understand you right, you are saying the LEDs you are planning on using drop 3.1 volt per LED? Can you let us know the part number for these? If you connect 4 3.1 volt drops in series, that will be 12.4 volts. If the battery is fully charged when you turn them on, they will draw lot's of current. When the battery voltage drops, they will shut off or be very dim. What you want is two or three in series with an appropriate sized resistor in series. It then sound like you are going to wire two or three of these series strings in parallel, is that correct? How big are these displays going to be? Are the LEDs mounted to something? A circuit board perhaps?
