I honestly don’t know much about that camera, but from a quick Google search, it looks like a decent choice. It is a point-and-shoot, though, which I’ve moved away from in favor of the creative freedom of choosing different lenses. Point-and-shoots have one lens that cannot be changed.
It looks like a good choice for maybe YouTubing and Instagram. I think the 4k quality sounds really nice, and post-focusing is very interesting and different from anything I’ve ever heard of. I’d like to try that some day.
As for the battery, most cameras don’t take “actual” batteries (like AA or AAA for example). They come with one large battery that you recharge. It comes with the charger port and everything. You just put it in the port and plug it into an outlet. Usually takes an hour or two to fully charge.
