Review on 🎮 FYOUNG Xbox Series X/S Dual Controller Charger Station with 2 x 1400mAh Rechargeable Battery Pack and LED Indicator - Replacement Charging Dock for Xbox Series X/S by Eduardo Long

All images show the battery pack as a single unit. This is the key to what I was looking for so I can change them quickly and efficiently. Unfortunately the batteries and cover are two separate pieces, there is a hole in the cover that the connectors in the docking station have to protrude through to make contact and charge the batteries. I suppose you could glue them together but I don't know how easily they will slide in and out of the controller.
