The input voltage is 5 to 12 volts. It can use two to four CR123 lithium batteries or two to three rechargeable lithium ion batteries (use protected cells only). The current draw is approximately 1 Amp at 6v and 750ma at 9v.
I know Gene likes to chime in here, so this is a question for you... (or someone else that knows definitively).
I'm looking at the MD3 body option for mine, so that I can run two 18500s or 3 RCR123s, you say it can run on 3 Rechargeable Li-Ions above, at full top off that'll come to 12.6V... Is that still safe for the Light as the voltage range is 5-12V? Don't wanna fry it
Cheers.

It will run with 3 RCR123's, talked to Gene today. Its going to draw 1 amp at 6V and 0.75 amps at 9V and 0.5 amp at 12V.
3 RCR123 only read 12.6V under no load condition. At 0.5A the voltage will sag and its not an issue. Gene has tested it to make sure its up to his very high standard of reliability.
Now for the really hot news for all those waiting to hear. The LED current is in the 1.40 to 1.49 Amp range. It will have a 22 ohm resistor in the low mode ring to allow 40 to 60 lumens based on the voltage used, so it will have a very useful low mode with excellent run time.
I should have one in hand for testing in about 8 days from 7/24/10. This will be very easily run on an MD2 with 2 standard lithium batteries (also 2 RCR123) or in an MD3 with 3 it should run 30% longer and the MD4 with 2X18650's or 4 CR123's it should run basically double that of the MD2.
