How about these drivers for 2S2O MC-E?

[kosPap]

I am assuming that these will provide 2x1000 mA total (1000 each) in 2 leds in a series, so on a Mc-e each die will get 500mA

So...
Two cell Li-ion battery LED driver (15W)
KD Keenan Driver

(the latter specs say:"Total input voltage must be 1-3V higher than output voltage, depending on the number of LED that you need"

thank you, Kostas
