With RC cars and boats as well as cell phones, you are charging the battery at high maximum rates (1-4C) to save on time. This is far more dangerous than golf carts charging at 0.15C. Charging at those high rates seriously degrades the battery life. The risk of thermal runaway is near zero when charging at 0.2C and below. I end my charge at 3.5V because the heat generated from 3.5V to 3.65V (max LFP cell voltage) is at its highest and the charge capacity gain is very small and the time it takes is higher...It ain't worth it.
What are the odds of a lithium cell phone exploding when being charged at 1C? Anyone ever have that happen to them yet? Fast charging is really only safe between 25% and 80% state of charge.
I doubt TV will ever outlaw gas carts. So what? To each their own. Hopefully 314ah carts will become available soon...That will be about 120 miles per charge. Maybe sodium ion batteries will replace lithium in the future.
