I understand that the 7T will be fast enough for me at 48V. Cell_man advises that the IRFB3077 (75V fets, up to 48V battery pack) would be better than the IRFB4110 (100V fets, up to 72V battery pack) if I am only going to run at 48V. However, is this only because it is cheaper? Or will the 3077 run smoother than the 4110 at 48V? I ask because I may want to use the 4110 for a nother motor down the road, or just try to pump 15s - 16s into the 7T on rare occasion to see what I get. But if the 3077 has an advantage at running at 48V, then I would like to get that one. Anyone with insight?
