What's currently the best, commercially available, technology for home batteries?

So minimize USD per kWh, at least 10kW power, little limit on size and weight, rather it don't catch fire easily. LiFePO4 still?
- Yes.
- LiFePO4
  
  Most likely. 10KW max output (not sustained?) and assuming you would want at least 40 KWh is going to be very, very expensive.
I wish they were readily available and had standard TI charging chip ICs to charge them.

Right now you can only get 18650s and a custom charging CC/CV solution.
