This is not G01 specific topic, but is general Lithium battery in car topic.

Many dash cam mention they don't use lithium battery inside, they have super capacitor so is much safer.

That make me thinking; Does it mean it is unsafe to leave lithium battery in car due to temperature in summer time?

I have those Lithium jump starter in my wife's car.
Also thinking of just put 2 X power bank in the back seat pocket because of lack of power outlet for 2nd row.

However I see many many dashcam mention they don't use lithium battery because of safety reason. BUT on the flip side, some brand offer external battery pack to use during parking mode. So what are those battery???

I think it is a very mix message. Anyone have good understanding on this?

While I do not really have a very good understanding of this, I personally refrain from keeping a battery pack in the car. There have been quite a few instances with battery packs catching fire (even outside the car) with the most recent one that happened in Canberra, Australia.

from the article:

Ms Mayes told The Canberra Times she noticed the battery pack, which can be plugged into the car to jump start it, popping open before it filled the car with smoke.

Interesting. I think F80/82/83 cars actual battery is Lithium Ion

It tends to be Lithium-ion batteries that have the problem and you shouldn't leave those in a hot car, the dash cam manufactures back up batteries wouldn't normally use those

Lithium-ion tends to be used when space is a premium, the dash cam back up batteries can be hidden away so can be larger, maybe the jump starter is the same?
