That's a 3 cell 11.2 volt LiPO pack. I am using the GWS/BP2S1P1300 2 cell 7.4V pack. The voltage they quote is nominal so when fully charged a LiPO pack will produce 4.2V per cell typically making the 2 cell pack 8.4V and a 3 cell pack 12.6V.
Batteriesamerica.com make an even better battery for our application it's an 1800 maH LiPO pack #2LP853560P4h its dimensions are 60mmX35mmX17mm and weighs 65g. It's only a 3C pack but if used only as a RX pack you won't need more current draw capacity than it is capable of.
If I used 6V rated servos I would use a 6V voltage regulator but I am running 7.2V rated servos so I don't. Normally when one uses a 6V Nimh pack with a 6V servo the Nimh pack is above 7V when fully charged anyway. For sure you'll run a risk of frying the servo by running extra voltage. I read David Joor ran LiPO pack straight through no regulator with his KO 2366 6V servos. He did say that there was a risk of frying his servos and the manufacture would NOT warranty them.
A thought on voltage regulators. It limits the voltage the electronics gets to the what the rating is, 6V for what we'er talking about. However, the 2.4V cut off the top of a fully charged 2 cell LiPO cell (8.4V-2.4V=6V) is not reclaimed or saved but is lost. That is you are just cutting off 2.4V from your 8.4V battery. That is a major loss in efficiency.
