Hey guys,
When should you perform deep discharge for the Mavic Pro battery? Will the DJI go app tell you?

Thanks,
Yhadar

This has been discussed before.  You do not want to discharge LiPo batteries too low as they can fail.  I believe DJI removed the deep discharge reference from the  Mavic manual.

That's right anything bellow 3.6Volts per cell on your drone will be too risky. That's why I never let any LiPo battery get lower than that. For storage purposes I will keep the battery at 3.8Volts per cell. If you really want to perform a deep cycle your absolute minimum shall be 3.4Volts per cell anything bellow that and you are in for a bad time.

Hello Yhadar, if there's nothing wrong with the battery, then you don't need to do the deep discharge manually.

Out of curiosity, what made you ask? Is AirData / HealthyDrones still putting the "deep discharge" on their battery maintenance schedule?

Nope, Just heard about it when watching phantom videos. Thought might be the same with the Mavic.

When reaching 3.6v, what percentage is it (about)?

Thanks,

When you finished flying your Mavic, just reload the battery, it's that simple, you won't have any problem

Sure, 3.6Volts is about 25% of the capacity of the cell. With LiPo batteries you must always be careful since the behavior of them is not linear, it's exponential meaning that the closer you get to the extremes of the battery capacity its more unstable.

The Mavic uses 3cell batteries meaning that it's working voltage is 11.1 volts. At 3.6volts you are at 10.8volts per battery pack which is quite unstable and the drone might enter in a power loss. This also explains why you must be very careful at low capacities when flying because any harsh input in the sticks and rapid acceleration of the motors will generate a power drop which the drone will not like, causing the ESCs to enter in a self protection mode and shutting down. Which will not be of any good if you are still flying.
Hope this helps!

Yhadar,

    AACY is meaning 3.6v per cell  x 3 = 10.8v --- I believe the flight battery would be flashing with
only 1 LED = plus or minus  25%

I saw a detailed youtube video on these batteries. One thing the guy said was to never charge hot batteries. He said to let them cool down first before recharging
