Do you have the TEMS or the FADEC ECU ?
I think I have manuals for both.. I haven't had to fiddle with the settings too much. If you got the TEMS version, I can go downstairs and read off the settings that I have. Currently have it dialed down to 124K, and that is way more power than I need...tried 126K once, and that was scary (the plane was not build for that kind of power..)
I'm using a 7 cell nicad pack. I checked on using Li batteries a couple of years ago, and they don't recommend them, only because they have never tested them. Certainly the way battery techonlogy has progressed in since that time, I can't see there being any issues...
