I have searched and cannot find an official statement of the C rating (max. discharge current) for the AW LiFePo4 RCR123A batteries. Various reports have it anywhere from 2C to 8C, but I suspect is is closer to 2C. Still much better than the Tenergys. I think I will toss my Tenergy RCR123A cells and stick with the 4 cell NiMH battery packs in my Prodigy. I'm happy with 5V and 4.8V is close enough.
