based on received telemetry messages since launch (units: volt / ampere / deg Celsius)
As the temperature is 7°C (2°C on the telemetry), each cell can roughly deliver 29W.hour. They have 28 of them, so a total energy of 812Whours.
Given that the 4M draws 3.5W (14V x 0.244mA + some losses), this gives us a minimum autonomy of 232 hours starting from 23Oct 19:18 UTC.
