Austin, See post #2 - I'll be doing higher charge rate tests shortly. As to commercial viability for eflight, this thread might help you decide:
The A 123s do accomodate greater power demand, in and out, than the contemporary generation of Saphions.
Speaking for myself, graphing LiPos has never been stress-free for me. They are too unforgiving of a mistake and voltage MUST be monitored, IMO. I do not agree with the staement on FMA's website with respect to their automatic LiPo charger: "Plug and Play and Walk Away".
It would be nice to rely on the digital readout of my CC/CV P.S., (I didn't do that while graphing, of course) without need of worrying about a little inaccuracy or drift, because of the non-critical nature of the A 123 and Saphion charging algorithm.
