So, in theory, 144v 120 Ah LiFePO4 is better than 144v 200 ah lead sled, due to the difference in Puekert's Effect and the difference in weight.
What are you looking at for 120Ah LiFePO4 batteries? Thinder sky's go 40, 60, 90, 100, 150, 160...

I would probably use the 160's. In the spec sheet there rated to 3C so thats 480A continuous, and 1600A peak. I dont think the high current pulls in the 1000A range would cause much damage to them.
