Not bad, not good; just average

These aren't particularly expensive, so I hate to fault the battery or its capacity for the GoPro hardware shortcomings, but when you design a product like the Hero series (6 and newer) with absolutely horrid battery life, you should make up for it by selling the extra battery packs at a very cheap price. The only reason I'm giving it four stars is because the third party knock offs are very questionable in quality, and simply aren't worth saving the few dollars.
Now, a word of advice; if you're on the fence about buying some of these for use in the snow, you will want to, and you will want to buy a bunch of them. The Hero battery life is horrible in the cold, especially if you're recording at a higher resolution and frame rate with image stabilization enabled. If you want even a remote chance of capturing a decent amount of footage on the slopes for a given day, you'll need a bunch of batteries. In temps below 30F, you'll be lucky to get about 10 to 15 minutes of footage per battery pack; seriously, at 2k / 60 with image stabilization on my Hero 7 Black, I have not been able to pass the 15 minute mark if the temps are in the 20's, and even worse if they're below that. I'm forced to load up with as many batteries as I can tolerate in my interior pockets, which tends to be about four plus the one in the device, and that gets me a whopping 90 minutes of recording across six or seven hours of slope time.
I'd honestly prefer a Hero that is a 1/2 inch taller or thicker if it meant doubling the battery capacity.
