If you want a better battery life - I would like you to suggest to go for a replacement door with USB-C passthrough and cable grove. Now, you will need a power-bank and USB-C to USB-C cable. Finally, you can remove battery from compartment and enjoy extended battery life along with GoPro heating issues. It works. With my 20k power-bank, I am able to record 2*256GB worth of footage with plenty of juice left in power-bank. Cheers
Hey @TravellerInParadise ! Thanks for your comment. Unbelievable to read how much you can record using that massive powerbank. BTW what is a cable grove? Cheers
