If low tempratures is such an issue with batteries why dosen't dji use the mavic cpu heat sink to keep the battery bay warm?
In higher tempratures the cpu fan can be used to ensure no over heating....

Also the way the mavic is designed means it cannot keep the batteries warm. So im unsure where you got this information from?

Flame,

The CPU and ESC is sandwiched between the battery and heat sink.

The battery and electronics produce heat when the unit in on.

The battery has no need for additional heat when operating, however it needs to start at a minimum operating temperature.

Am I misunderstanding your question?

Flame,

The cpus are sandwiched between the board and the heat sink which is the base.

The heat will not get to the battries due to plastic surrounding them.

Flame what's your point?

The system is designed to move heat away from the producers, not toward.

There isn't an issue KEEPING the battery warm when the drone is operational as long as it didn't start too cold.

Last weekend we flew on a cold windy day and saw battery temps around 44c.  On warmer days I see it closer to 52c, regardless there's no issue keeping the battery warm when flying the drone.

The Batteries generate heat when they are in use.  As long as the batteries are near room temperature when they are turned on, the Mavic should be fine flying under 32f/0c.... There are videos which already show the Mavic flying under these conditions...
The trick is to keep the batteries toasty in a warm bag before putting it on the Mavic and quickly starting it up.. Once it's up and flying, the heat generated in the battery will keep it going..
