Sounds similar to what I was envisioning, albeit a little simpler. Since I can't read German (and much is lost in translation), do they also test lipos in "car mode"? Meaning, do they test the lipos with fairly low average current and then spike the current to 8X the average? This is what cars typically see. A battery that can provide a steady, but high current, may not act the same when subjected to car-style loads.
