does some pretty intensive testing of lipo's. It's in German so you'll have to use g-translate to understand. All the packs are monitored during the same discharge sequence: 3x50s: 10C / 3x5s: 25C / 1x60s: 15C / 1x5s: 20C: / 10C till the end of the pack.
Also, the packs temps, internal resistance, and capacity are measured.
