But since lithium is an extremely active metal, always a potential
fire hazard, and an active one if the electronics don't do their job
correctly.  And class D fires are hard to put out.  This has already
become a real issue with cell-phone and laptop batteries using
lithium.  I'd think it would be preferable to relocate such batteries
outside the passenger compartment...
