Energy storage - New gen batteries

Places like Tesla, one of the highest tech car companies in the world, still get fires in their cars from time to time and so does every laptop manufacturer out there. Tesla use titanium shields to protect people, they know the hazards. They have extremely advanced charging and temperature monitoring systems, yet still some catch fire. I think they are the way of the future, but I would not go in without investigating the very real issues and making sure the risk is contained.
I note the smaller batteries they advertise seem to have more built in safeguards than this one, may be a better choice. Not sure.
