well anyways, i went and used the formula the manual gives for calculating resistors - and i also used an online led resistor calculator - and got different answers. the manual says; R = (Vpack – Vf die) / FoC current ---my tri cree rblue diode runs 3.41v @ 1000ma/1A ----- my battery is a 7.4v 1400mAH ------ so that should be R=(7.4-3.41)/1 ---so----- R=3.99 - yet the online calculator says 4.7ohms 4.7watt resistor. Which is correct? and then the lowest i can find on TCSS is ??ohm at 5 watts.
