Mini 3 Series Intelligent Flight Battery Plus (2 Packs) with Bi-Directional Charging Hub for DJI Mini 3/3 Pro/4 Pro

This is the one I got - https://a.co/d/00YLKvCE But there are a few. You can also buy 2 OEM batteries from DJI ($65 a piece I think?) then buy 3rd party hub or OEM hub for $45. I took the risk on 3rd party ones but working great so far 🤷🏼
