I consider using A123 on my receivers analogous to the fuel tanks on my planes.
Since many of my fuel tanks are inaccessible when the plane is assembled, I will measure the amount of usable fuel remaining or the amount required to top it off after a flight of a known duration for the first couple flights. I then have an indication of how many minutes I can fly before things get real quiet.
The same thing with A123's. Charge the battery and then fly a couple flights. Put the battery back on the charger and note the mAh's required to fully recharge the battery. If you put 600 mAH's back in the battery after 4 flights you have a good idea that you can easily fly 8-10 flights. Personally, I charge my A123's before I go to the field and they are good for the day.
I believe the relatively flat discharge curve is a benefit.
