The charger for Agras T40 and T30 drones is the same and that charger can be activated either with the DJI assistant 2 for MG or with a DJI Agras T30/T10 remote controller. The charger needs to be updated to the latest version to be able to charge the Agras T40 batteries. T30/T40 charger: talosdrones.com/products/dji-agras-t30-ultrafast-charger
