Normal Flying Battery Temps?

[Thundr]

What are your maximum flying battery temperatures on the Mavic Air 2? And what do you consider "normal? Also, at what point, do you call off a flight and return home due to high battery temp? According to Airdata, my max recorded battery temps are:

• Battery #1 - 131.9°F (55.5°C)
• Battery #2 - 130.1°F (54.5°C)
• Battery #3 - 129.0°F (53.9°C)

All normal. You will see >60 Celsius if you get the cells down toward 3 volts per cell (9/total). The volts are the important number for when to come home, not the %. No LiPo batt should go below the 3volt/cell landmark. This includes stored batts. DJI has a very conservative algorithm for their batts, sending you home at 3.5 volts, I think, on the mini. You could push the limits on that with plenty of reserve. I have had my M2P/M2Z at 0% batt but the volts were at 3.3-3.2 volts/cell. The RTH of course was activated but I could override it. The only issue with the higher temps is lithium oxidation of the LiPo cell. LiPo is already at a disadvantage compared to NiMH and are only good for 150-200 cycles, so the more you let the cell run down, the higher the temps, and the more oxidation, the less cycles you will get out of it.r
