| Thundersky and Sky Energy large format prismatics are going for around $1.10 ah in bulk purchases. This puts a 20kwh pack at about $7K. 20kwh packs would get you 80 mile range assuming average 250 wh/mi., Large auto companies could certainly get a better price than that, plus the LiFePO4 prismatics need less cooling, fewer connections, and no thermal runaway management, making the whole pack design cheaper. Density is improving with these cells as well, 190ah cells are the same size as 160ah cells were a few months ago and C rates have gone up.
