Ok, so I'm using this diagram:
2010ModifiedNoVoltRegrev01-10-2011.jpg
with Royal blue rebel star: 3V(forward) 1000mA forward current
battery: 3.7v tcss pcp Li-ion
LED resistor: 1ohm 2watt http://led.linear1.org/1led.wiz?VS=3.7;VF=3.0;ID=1000
2 questions:
did I calculate the right resistor?
Is there any advatange/disadvantage between the 3.7v and 7.4 battery setups for econo boards?
