Hi, My 2nd Hero 8 Black battery bloated today. The last one was almost a year ago. I use my GoPro at least 3, sometimes more, times a week doing short scent work training videos with my dog as well as during competitions. It looks like the last one I replaced was on Amazon after not finding any available on the GoPro site. I just noticed that the one I bought as a replacement says it's refurbished, but I can't find any OEM or new batteries for the Hero 8 anywhere. Does this mean I need to consider replacing my Hero 8 so I don't end up without a battery when I most need it? I bought the 8 when the 10 was new so that I could buy a less expensive model. Advice?
