According to their spec sheets their lithium batteries are LiFePo4. I didn't know anyone in the US was still making those. I know they are made overseas for some US companies. Don't like the fact that they use the "designed and assembled in US" terminology. It kind of implies that the cells are manufactured here too. I couldn't find anywhere that was stated but I would love to see otherwise.

Voltage levels are a bit different from past versions of LiFePO4 also. They charge at 3.5 volts. Most of these cells used to charge at 3.6 volts and had an effective voltage of 3.2v. Suppose they could have tweaked the chemistry a bit or maybe they are using different cathodes and anodes now.

You're right about them being high priced. $700 to $1000/kwh is up there.
