The A123 batteries are a name brand for LiFe type chemistry

http://en.wikipedia.org/wiki/A123_Systems

LiFe batteries are a great option for running your heli without a voltage regulator if all your servos are rated for 5 Cell NiMH or NiCD packs. The voltage from a 2S LiFe pack is about the same. I've used LiFe since 2008/2009 and had great use as long as you pay attention to how many flights you run. You can't judge capacity left by voltage and when they get low they go flat almost instantly.

The 10 amp castle is not your best choice. It is not really rated for 10 amps. I had one if Castle's BEC pros on my raptor but I also wouldn't recommend that one either as both positive wires broke off right where they were soldered to the board. That led to a nasty crash

I have been using Fromeco regulators. Those I will recommend.

A123 cells are 30C due to the magic "nano" structure. They are not the same as LiFe prismatic cells which are 5~10C. You can tell if they are discharged. Search my USER NAME and VoltMagic. I have been using this for about a year. Requires some testing and calibration.
