I read through a few recent threads, but it seems like batteries in the 6v/9v option are harder to find than they used to be. I have this currently, at least, this is what it looks like:

When I bought it, it was sold under the name PowerBank MP20000A (I'm shocked to admit this, but I just looked at emails and I think I bought it in 2011 - I'm not sure that's true, maybe I bought a second at some point, but it's certainly possible). It has a button to select the voltage and I set it to 9v when running the v2. There's no power switch, which I like because it's one less thing to bump at a show. Then at some point I found it as "RAVPower 23000mAh Portable Charger Power Bank External Battery Pack(Xtreme Series,3-Port,9V/12V/16V/19V/20V - LCD Display)" when recommending it to someone else (2015). Now when I look at Amazon, I don't see any selectable voltage packs. I think I can change the v2 to 12v, but won't it just blow that voltage off, aka heat up? I see the Talentcell options, but they only have a 12v barrel output.
I just bought a Sonosax sx-m2d2, which you can power with USB in addition to the internal 18650. I was thinking I'd buy a new version of my current battery because I don't know that it'll last my running a v2 and m2d2 on USB for a whole show (running DPA 4023s and 4028s).
Is there a good option out there for something that'll do a barrel DC out and USB simultaneously for 6v-9v? Or can you run a v2 off of the 5v from a USB plug?
Thanks!
Evidently I can't read. I thought the yellow plug was for input only, I see now it says 9v output on that one and 12v in/out on the black barrel:

This is the TAlentcell we use to power two V2's and a V3. I have two of them and kindms has at least one.

This is what i use and a 4 hour show only drops one bar on my V3.

I have the exact same setup for my v3. Nice batt....
I'm thinking about bringing my v2 out of retirement. Is this talentcell still the best option?
Also I'll need to hack an old power cable from a long dead battery. Is the polarity an issue with the v2?

Don't forget the power in on the V2 is a 4 pin XLR connector. maybe PM Ted to see if he has a schematic or something.
Thanks. I have a 4 pin xlr cable that went to the output on an older battery. I was going to terminate the battery side but don't remember if the v2 is polarity specific.

From Ted's post in the remote power sticky
Grace Design Lunatec V2 (6v Version) / 6-12v / 4 pin XLR Female / pin 3 for (+) pin 2 for (-)
Grace Design Lunatec V2 (12v Version) / 4 pin XLR Female / pin 4 for (+) pin 1 for (-)

POWER SUPPLY CONNECTIONS
A four pin XLR connector is used for the DC power input of the V2. The V2 can be ordered
to operate from either 6 or 12 Volt power sources. Pins 1 and 2 are ground and pins 3 and
4 are either 6 or 12V DC. To avoid compatibility problems it is recommended that 6 Volt
systems be wired to use pin 3 for hot (+6v) and pin 2 for ground while 12 Volt systems
should be wired to use pin 4 for hot (+12v) and pin 1 for ground. The V2 current draw
ranges from .38A to .62A depending on the microphone used.
