Tesla's Powerwall

So I just saw a little diddy about this new product from Tesla called "Powerwall"


Basically a huge Lithium Ion battery. Word is that it can be coupled with solar energy to power your home during the day, and it charges up at night when energy companies (apparently) charge less, ultimately saving you 25% on your energy bill.

Is this a case of too good to be true?

At first glance, I seem to recall that these types of batteries are prone to spontaneous combustion.
