The big snag with Lithium batteries is their nasty tendency to catch
fire spectacularly.

 
 
You can design the battery monitoring circuitry to prevent them doing it
spontaneously. Electric bikes and the like may not be big enough to
justify the expense, but electric cars and domestic solar panel back-up
batteries certainly are.

I'm less convinced of that than you are. I think you can pretty well
stop thermal runaway but only iff the sensors are done properly.

A tiny dendrite puncturing a separator can start an ignition wave that
propagates in all directions at centimeters per second and ends in a
fireball fast. All a sensor might to is to tell people to RUN.

Utility-scale batteries are huge and forklifts move pretty slow.
