The $0.08wh is something that you have to hunt around for.
Just a cursory look on Aliexpress gives $0.12wh for LiFePo4 batteries [0] [1].
Looking on Alibaba, I see some potential sellers that might get below that $0.12 but it takes looking around and potentially talking with sellers. I do think it's possible but it requires some hunting, especially in the 'consumer' quantities we're talking about (sub qty 100).
