BATTERY_INFO msg

Hi, I would like to ask about this battery_info msg (Messages (common) · MAVLink Developer Guide) status? I have these smart batteries Tattu Plus DroneCAN Battery — Copter documentation, but I dont know how can I get the info about those from drone. I would like to track my cycles per battery serial number and so on, but I am unable to get that info. I tried to request the battery info message via pymavlink 2.4.41, but got message that that one is not supported. Can I get that info about battery sn somehow differently?
