One of the hassles with A123 is setting the LVC. Most ESC will only do lipo or NiXX (Castle with the USB programer being one exception). Neither are quite exactly what you want. You can LVC them to 2.0v/cell without problem. Sometimes the best option is NiXX, or like Jack suggests...pay attention and land early.
But....one of the big problems is when they go dry.....they go DRY! Re-arming the ESC may only get you a very weak and short term result.
The 1100mA are just not up to the specs of a decent modern lipo pack for small planes, and the 2300's pretty much are too big until planes get over 3# or so.
I used to use the 1100mA but don't bother anymore, not worth the weight penalty, size restrictions, and LVC hassles. Good batteries though if you can find a place for them.
