I think I may be a bit confused. If a single 40 Ah cell can provide 80 A (for a little while), shouldn't 45 of those 40 Ah cells be able to provide 80 A * 45 = 3600 A? That 80 A would be at 3.2 V for 256 W. All 45 cells would be at 144 V, for 518.4 kW or ~ 500 hp. That's three times the power of the 260 Windsor engine in the car today, and substantially more than you're going to get in a stock muscle car of any era -- and waaaaay more than even a pair of AC-50s or WarP 9s is rated for. So...does discharge scale with the number of batteries, or is it limited by the discharge of a single cell? If the former, I should be more than fine with a 45-cell pack of CALB 40 Ah batteries or equivalent. If the latter...I'm likely screwed....
