I don't know what is 10%. I fly stock app and there is no number. I fly til it says battery critically low and it tries to auto land. When it auto land I use sitck up to counter that to get more air time until it says ah feck it I have no juice error 13 and just lands anyway.And that's with the Tello auto landing when the battery reaches about 10%?
I wasn't aware you could override the autolanding feature on low power. Definetly something I will try tomorrow.I don't know what is 10%. I fly stock app and there is no number.

It seems tello is programed to land efore the lipo life hurting low voltage.Just FYI Lithium batteries are sensitive to under and over voltage and you should avoid discharging it under certain voltage. It kills them pretty fast. It can be dangerous also. So if mine is saying it needs to land, I let it land.
And in winter your flight time will be much shorter. Like 1/2 of the usual. I flew outside around 0°C and log in brilliant app of Mr. @volate!lo TelloFPV told me, that batteries lasted only 5 to 6 minutes instead of usual 11 to 13. That is because the chemical reaction in the battery needs ideal conditions to perform their best. So too cold and it won't last, too hot and it could be dangerous (won't happen with Tello, unles you do some extreme stuff).
It is possible to fly below 10 with TelloFPV.... You activate "Throttle up to cancel auto-land"... I have landed at 2 before when I got carried away and didn't allow enough battery to get backNot possible to fly below 10%. To get 13 mins flight time, you need to be in a windless envirorment and take off prop guards.
So how can we determine on which stage of a luner eclipse it helps improve the battery % of landing?Tello decides when its time to land. There seems to be two trigger points from my experience.
1) Around 10% battery triggers autolanding but you can cancel this as jesusfreak said
2) Tello seems to calculate a remaining "safe flight" time. Once this is below a certain threshold this triggers an autolanding that can not be cancelled. This can be triggered before or after the 10% have been reached, depending on you battery health, the current power consumption, temperature, lunar eclipse, ...
You are flying with a battery that says 20%, you fly to 10% and autolanding kicks in, you cancel this and continue until maybe 7% before Tello finally lands.
Or, you put in a weak or depleted battery. It shows 20% at rest. You takeoff, and internal voltage drops very quickly. Tello still reports maybe 16% but decides to initiate autolanding that you cannot cancel.
