Wild guess -- we will soon be using Tesla batteries for RVs

Lithium batteries are often used in Laptops. If you have EVER taken one apart there are more sensors in there than you can imagine.. Every battery has two sensors on it to insure proper charging and discharging.

Many computers have had battery recalls due to thermal runaway setting the thing on fire.

And that.. Ladies and Gents.. Is the major issue with LI batteries. One airliner was grounded (not one plane but every plane of that make and model)due to Li Battery fires.
