I am a bit cinfused. Are you talking about the brand A123 who are known for their LiFePo4 batteries or are you talking about the CR123 dimension batteries?
The CR123 dimension is the same as the 2/3A cells which are used in many NiMh receiver packs.
I have looked into the CR123 LiFe cells but They are not the ideal batteries to use. They are low in capacity and are no real high current providers. Even when building a 2S2P pack it still will be questionable how it will work. I am looking into the 14650 LiFe cells which can be found with a capacity up to 1200mAh, light weight and, handle currents up to 10A (the right cells) and 2 cels are like a receiver flatpack (used in many onroad and several offroad cars)
