GoPro
I bought a GoPro HERO 8 BLACK at Costco just before my Rt. 1 trip from Boston to Columbia, South Carolina in March 2021.
I managed to lose one of the two batteries after the trip. I use the camera mainly for cycling, skiing, and road trips sometimes.
The battery status in November 2021:
Activity: | Temperature (°C) | Battery Life (minute) |
