Hello!Yes, it has and it works. I was just surprised, why it doesn't work with the b.b. And wouldn't be there any benefits from using higher pip voltage than the 1,5 V internal battery or 2,5V's of my H2?

And wouldn't be there any benefits from using higher pip voltage than the 1,5 V internal battery or 2,5V's of my H2? Because it uses the 1.5v through a different circuit. That is bias power. The other is phantom power which is (relatively) standard at 48v. Usually the phantom circuit can take 9-48v. It then brings it down to a usable voltage. A battery box will not work with this mic unless it supplies significantly more power than the standard battery box.

A battery box will not work with this mic unless it supplies significantly more power than the standard battery box.This mic does not operate from Phantom power. The battery box does not work because of the dc blocking caps at the output of the mic are preventing the external battery from powering up the capsules. Remove the caps bypass the 1.2 volt battery and you can externally power these mics with plug in power although I doubt any advantage will be gained from the external battery the mic will most likely overload even after all these modifications more bias power does not necessarily guarantee less distortion.
Now I'm totally confused... It does work from 2,5 V pip provided by H2, but it doesn't work from 9V provided by b.b.? Huh? If it has caps on the output, how can it work from H2's pip?
4,7 k resistor, as in the schematic above.
