PS. I noticed one website that says that lion batteries should not be frozen. They freeze at around -40 C, which is also coincidentally -40 F.
I remember listeing to Dr Carl on radio and he said that neg 40 is where the two tempreture schemes cross over so the conversation could go like this:
“Lion batterys freeze at negative 40 degrees”
“Is that celsius or fahrenheit?”
“Yes”
