A123 LiFePo4 cells have a resting voltage of 3.3-3.4 and a very flat discharge curve, unlike the Li batteries that I have seen so far, and very high C ratings. This also would seem to match closely with the Vf spec of the XML (understandably some variability is there). My driving force of this is to make my first modd without much effort. I don't have much experience.
Any help is appreciated.
