If you want even less weight go with the A123 1100mah version. I bought some VPX drill batteries using them and they cycle to ~900-950mah.
I pretty sure these are not the Nano Phosphate that the 2300 mah are.
I ran my ignition on A123 2300mah, and powered my radio with it at the same time. I read it works on GHz, and I did it on my Futaba 9c using PCM by accident, my ignition battery was dead so I just took one of the radio's power leads and plugged it in so I could tune my engine, then forgot and flew it that way. I didn't see any glitches, but it's one of my favorite planes so I didn't risk it again. I plan on doing it intentionally in a junker.
The ones I have are nano phosphates by a123
