At temp like today (low -5, high 9), using a 4 battery pack in my jacket, I can comfortably go for about 1.5-2 hr. But I wouldn’t want to use the battery a second day without charging it again. [These are good quality Samsung batteries with a controller circuit built into each battery.]
If I place the battery at the ambient temp, I’m sure it will get less time out of them.
