Batteries can be had in smaller amp-hour sizes (25, 40, 60 amp-hour) so you can avoid the boost converter (more weight, lower peak current) if you are OK with double or triple the battery connections. 320V of LiFePO4 cells is 100 in series. Using 40 a-h cells, you get a 12 kw-h pack. Not sure what sort of range you are looking for.
