I recently purchased a Hero 8 Black, mainly to video my kid's games. I haven't had a chance to try it out until games start in the spring. My plan was to attach it to the fence and let it record. In my testing at home, the camera seems to get pretty warm after extended recording, so my concern is that it will shut down due to heat while I'm recording games. I've shut off all the bells and whistles and that seems to help a little with heat, but it's also 68 degrees in my house instead of 85 degrees like it will be during games. My question is, has anyone tried running the Hero 8 with an external battery pack, and does that help keep the heat down inside the camera? Also, if anyone has used theirs to video games like this, any advice would be appreciated. I'm hoping to have it figured out before the season starts. Thanks.
