i have been testing sound samples of what seems like thousands of mics/pre/recorder combinations for the past few months, i finally have the $$ and will be pulling the trigger sometime next week on Beyer MC930>V3>DR100
a couple of questions about the V3- is it battery powered? or if not, how is it powered in the field? also what is the difference between the 6 and 12 volt version?
-
The V3 takes anywhere between 6-12 V. I use a Tekkeon 3450, and others use a DVD battery that typically outputs 9V.
You need a special DC-in connector, ie., it isn't a typical one that you can use one of the adaptaplugs that come with the batteries. I think tgakidis has some of these plugs and can make you a cable.
The only difference between the 6 and 12 V versions is when the "Low battery" light comes on.

i have my eyes on a 6volt V3 on ebay, would these products be sufficent- i will kind of be in a time crunch so i want to order as much from the same place as possible
http://kindkables.com/catalog/product_info.php?products_id=12 (6 volt, 4.2 amp hour battery)
http://kindkables.com/catalog/product_info.php?products_id=29 (lithium ion power cable)
or if not, could some kind soul post a link to batteries/cables that will work for a 6 volt v3, as some of this is confusing to me ???

Good luck running a V3. I still really miss mine sometimes :(

Definitely suggest Ed (Kind Kables) for your cable making needs.
For battery power get a Li-ion battery. The one you have linked is a Lead Acid. While it will power the V3 fine...it's a tank. It's pretty heavy and doesn't hold a charge as well as a Li-ion battery. The Li-ion batteries will hold their charge for a long time (handy for that spur of the moment taping) and are pretty light.
It seems that most people use the DVD style battery. I just got the Tekkeon MP3450 which is really nice. It will power devices with a variety of voltages (although only one voltage at a time). It's a little more pricey than the DVD style battery though.
Not sure on the deal with the power cable with a V3 and Tekkeon battery. Hopefully someone else can chime in on that.
Here is a link to the Tekkeon:

I use the Tekkeon with their "B" connector, which fits the V3 fine. The only gottcha with this, as well as with the official screw-on V3 connector, is that over time the central prong on the V3, which has a slot in its center, will push together and cease to make a good connection. You just have to use a screwdriver to push the halves apart a bit. There was a link on the Grace web site showing a way to deal with this by cramming a rubberband slice into the slit. But I have an early machine, maybe they fixed this in more recent production.

The initial Power Stage on the V3 uses a Linear Regulator so it will run more efficently as you approach 6V. This means if you use a battery like a Tekkeon you should run it at 6V versus 9V or 12V you will get longer run times and the V3 will produce less heat.
You can contact grace about changing a 12V version to 6V - There are a few jumpers and pots that need to be changed/adjusted to make this work.

I wouldn't spend money on lead batteries unless I had a specific need. And surely there are better ways to wear out your back. The v3 is easy to power.
The RB-270 lithium batteries were classics. 5400 mah at 9 volts. That will easily run the v3 six or maybe eight+ hours? I paid $10 for my last one on ebay, but $30-$50 was not uncommon. The new ones seem to be gone :(
There were also 7 volt versions, which should have bee even better with the v3.
That lenmar dvdu923 battery looks okay, but it's only 2500 mah. That's kinda low for the price.
