I was thinking about to change the cree R2 (now in my powerled) for a cree MC-E (I know that the original PL optics don't work for the MC-E, but I will put a "good" optic for MC-E) but, only with the electronic thread, what configuration would the better to run the MC-E led, all in series, I think that not, since I need 3,7*4 = 14,8 volts, maybe 2p+2p then I need a 7,2 (really 8,4 volts of the Li-ion battery) for each 2 groups of leds, if the KSQ of the PL work to 1000 (I think) then the MC-E led will work to 7,2 volts to 500ma x 2 (4 leds)....you think that this configuration would work with the PL??....help please...
