Their quoted price of $375/kWh is good, this shows the advantage to volume purchasing. Last year, I paid $445/kWh total out-of-pocket for my cells, including BMS modules and shipping to my house. There are multiple vendors in the US that will sell you LiFePO4 battery systems of almost any size (small orders) at less than $500/kWh today. I would consider this to be the industry average right now.
I can order 24kWh of bare LiFePO4 160Ah cells today for $9,200 before shipping and BMS.
That said, there are also vendors selling systems at more than $1200/kWh. It pays to shop around.
