I have purchased this specific package twice for my Nikon D500 and I can say that they perform much better than the official battery that came with the camera in the package. I have not encountered any overheating issues while using these batteries, however, I only use them for photography and not for video. Whether for the main battery pack or as a backup, it is definitely worth 100% of its money as it comes with a charger and a car adapter in the package.
