Hello Yono,
Thanks for this information. One the battery voltage gets down to about 3.6V (think that's the value...), AO-91 will go automatically into safe mode. The values of "MIN" in the telemetry logs will help to tell a more complete picture. It's reporting as low as 3.31V now. So yes, it's behaving as designed and engineered!

Dear all,
For the third evening, AO-91 satellite flipped to Safe Mode during the 10 PM (15 UTC) pass over Indonesia, before reaching TCA.
Reading the telemetry, battery voltages are ok. Anything else that tripped the sat into Safe Mode?
