Patrick, I am not sure that D2-Pak7 has smaller die than SO8-FL and its current ratings are not that shy. And I agree on SO8-FL vs. LFPAK's.

Personally, I am looking forward to use DirectFET package, you can heatsink them top&bottom equally. For 30V ESC.

I do not see why software can be so complicated, 10 years ago maybe it was an art to make brushless sensoreless, today with all bells and whistles inside micro's and all the features... Cannot believe in that... Neither I have seen chinese ESC with as smooth performance as schulze...

Nice plans for:
8S 200A ->6720W
12S 125A -> 6300W
8S 325A -> 10920W
12S 200A -> 10080W
Just keep wondering what kind of capacitor (size wise) you are planning to use to absorb punishment. Even 2% of 6kW would be 134.4W - that is pretty good size for capacitor...and 2% is nothing you know. Or you plan to have batteries implanted inside fet's :)

Did somebody said something about sensors ...Hmm - > Marketing or Hype -> must be crawlers
