Sure did, and there's no need to modify anything. I just put the battery pack in my pocket and let the tiny clip wire run down my side when I'm using the TIR clip on my G930. (I can still get up, go to the bathroom, make a turkey sandwich, return to the computer - all while never leaving the conversations since the G930 also have G-keys that can be mapped for PTT in Ventrilo).
Here's the lithium-ion battery pack I got:

As far as headsets, I used a Fatal1ty headset (~$80 new - I'm sure they're less today) for years and never had any issues. One of the best I've had... but now, with the G930, it's stored away in the closet as a backup.
