That's what I'm doing now . The only thing is that a preflight load test isn't as valuable as with a NiMH pacK . The A123's have a very sharp discharge curve at the end . I still test just to check pack integrity under load . I initially do a few flights and get an idea of mah use per flight and then calculate the number of flights I can get when using 70% of the capacity . The batteries charge so fast that I usually do a few flights then charge while shooting the breeze.
