Has anyone else experienced their Inspire 1 Pro TB47/TB48 batteries giving you an erroneous "Critically Low Battery Power" warning and initiate RTH?  This has happened to me 3 times with 3 different batteries, all of which have a battery life between 85%-87% and between 65 and 70 charging cycles, according to Airdata.  One of the batteries is a TB47 and 2 are TB48s.  The warning always happens within the first :45 seconds of flight.  Once I land the aircraft and power-cycle it, the problem goes away and I can fly normally with the same battery.  These batteries were all purchased in June, 2016 and have manufacture dates between 10/15 and 1/16.

While this happens, did you you look at the individual cell voltages in the GO app? Do not rely on the battery % display.

Hi, Sky2PIC. there are two possible reasons for this message:
1. If powering on the battery in low temperature conditions and the battery does not reach the ideal temperature, the voltage will decrease sharply. Then, the app will display "Critical Low Battery Warning" and force the aircraft landing. It is recommended to keep the battery temperature around 20 degrees centigrade.
2. If fully pushing the sticks when the battery power is low (about 40%), the power output is too large and the voltage may suddenly decreases.  We recommend to slow down the speed.
Please let me know if you experienced these two situation?

To Keule and DJI Mindy,
Thanks for your interest...here's the data taken from my AIrdata account:
Keule, the individual battery voltages for flight one were 3.263v, 3.18v, 3.079v, 3.233v, 3.221v, 3.295v at roughly the time of the warning, which again was :41 into the flight.   The voltages for flight two did not have any deviations so individual voltages were not recorded and for flight three they were 3.226v, 3.201v, 3.173v, 3.19v, 3.101v, 3.211v at the time of the warning, :43 into the flight.
DJI Mindy, at the beginning of each flight, the battery temperatures were, 17.4°C (63.4°F), 18.2°C (64.8°F) and 15.8°C (60.4°F) respectively.  The temperatures of each climbed to and above 20°C at :18, :20 and :32 into the flights, respectively.  All three batteries were fresh off the charger and all three indicated 90% at the time of the warnings.

From your cell readings, they are way out of balance. You should not use them anymore. Try to keep the cells within 0.05 deviation. Anything out of that range will have critical consequence.

To me, the batteries are in a no good condition.
I assume you are talking about 3 flights with 3 different batteries?

a) The given voltages are way to low. (LiPo's must never be discharged below a certain limit.)
    When under load (flying) individual cells should not drop below 3.0v! Your Voltages are very close to that limit.
    I handle my batteries in a way that i am on the ground/landed at 3.5v
b) Your cells are not balanced well. Cell #3 for example shows a deviation compared to cell #6 of 0.115V
    More than 0.06v between the cells is not acceptable.

You should try to deep cycle all of your affected batteries.

Do not fly with these batteries.
