I replied to your post in the Line Audio thread but here it is again - I can confirm that the CM3 (almost exactly the same mic) will run just fine - with reduced sensitivity and corresponding output - from 12V phantom power.
Whether it will work with something other than a preamp that supplies power is anyone's guess. The current consumption is <4mA so it's conceivable that it could be done with a 12V battery with sufficient capacity but only if the mic is not picky about the filtration applied to the power.
