I would think the tabs would have to conduct the burst rating of the pack. I mean the sustained rating is 150amps, and the continuous is 100...
So far this is the best arguement for high voltage I have seen. No matter how good the cell is, if the tabs can't handle the load, better run more volts and less amps.

Sike and I came to the conclusion that there is no way that the thin little tabs could hadle the spec discharge numbers, just not going to happen. High voltage is a much better way to go. My 8s savages with the 14xl feigao runs 3600 12c poly rc packs (around 45 amps cont) and has no issues. Motor gets to around 140 and stays there for a 30min run. The 60 amp esc barley gets warm, maybe 110, and the batteries are around 105 when the run is done. It is a heavy truck, and has plenty of power, more than my 7xl 4s revo.
