  yeah those battery cells run \~$10k when I was looking into solar, and I don't think they have a long lifespan for the cost.
context: Whatever happened to their home battery system?  I was sort of looking forward to that.
  ETA: Oh I see they still exist (Powerwall) but not sold through Tesla and cost a mere fortune here in Canada. >
  
  They are only selling Powerwalls with solar installations in the US.
