or will it do an adequate job for a beginning FPV'r?

Thanks for all the awesome answers. OK forget that one.
I ended up buying these:

The cam I'm not too concerned about, the "Boscam" I understand will be a counterfeit from China, and the low cost HK headgear is actually pretty nice for the money involved to get it. My question is, what MAH battery should I use to power it all? I plan on using a 3 cell 11.1v Li Po. Can it be low discharge rate like 10c?? I'm looking at getting two of these: http://www.hobbyking.com/hobbyking/...2500mAh_3S1P_5_10C_Transmitter_Lipo_Pack.html
How many flight batteries (@ 6 minutes flight time per battery) will this 2500 Mah battery last for while powering my RX and headgear. The RX working current is 200 mA @ 12v. The HK headset unfortunately does not give anything more in the way of specs than input voltage 7-12v. Let us assume that it draws 400 mA (and possibly more.) Any electrical genius types out there willing to help the less fortunate? Too much figuring for me to get it. Any feedback is more than welcome. At the very least I would like to know the answer to the low discharge battery question. Thanks in advance

The low discharge should not be an issue for your ground gear. At 2500mah it should last a while - and hopefully not add too much unwanted weight if you're strapping it to your headset .
I think the common goggles/headset batteries are a good deal smaller/lighter than 2500mah. Maybe 350-400mah.
I was able to power my 7" monitor, small DVR and video receiver on an old 3S 5000mah battery longer than I wanted to fly. So depending on your stamina - maybe buy a few spares.

I never fly for more than an hour at a time (yet at least.) Based on your optimism about the lengthy battery life using that 2500mah beast, I decided to go considerably smaller and settled on a 610 mah 20c that I could get at a better price so I bought two. http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=58544 It also comes with a JST connector which is what I believe the RX has and I know the monitor has.The low discharge should not be an issue for your ground gear.

If I can get an hour uninterrupted (other than the battery change) from these two 610 mah ones I'll be happy. Sound possible? Device draws 200 mA. Battery stores 610 mah. Should be 2 or 3 hours on that battery alone. Add another device that draws 400 mA. Battery now lasts an hour. Use a separate battery for the monitor and for the RX at the at the same time, should be 2 or 3 hours on the one and 1&1/2 hours on the other. Roughly? I think I have that right.

Keep in mind that you will not be running down the battery to zero, so your estimates will be a bit off. You're probably looking at under an hour for the batteries, but you'll have to power everything up to see for sure.

Right now I only have the ability to do four 6 minute flights before I need to recharge my entire stock of flight batteries. I think I'll still be ok. 24 minutes of flight time on a long day for me.

You should be fine. You mentioned 1 hour which would probably be pushing it.

When I go to get more flight batteries I will also buy another couple of those 610 mah ones as well. Thanks for your help.

That's the best bet. Cheap enough to have spares.

Finally powered it all up and it turns out that it runs the battery from a full 4.2v down to 3.87 in one hour on the RX and down to 3.9 on the view screen. So I'll be able to go right around two hours before needing a recharge. I can live with that. These 610mah batteries are small and fit on the brim of my headset hat combo that I created. I'm glad you mentioned the smaller 450 mah batteries that other sets use. I would have overspent and over powered with that big battery I was looking at. These 610 mah batteries are perfect.
