Now that winter season is upon us I won't be flying as much. My concern  is, does it hurt to charge the Mavic Pro Intellegent flight batteries just  partially say around 50% instead of 100% just for storage purposes? Will  this shorten there life cycle? Right now acouple of them are down  around the 12% level.

Charge them fully and set the software to discharge them sooner if you don't like the 10 days.  Better to fully charge and then discharge to <50% than to charge them up to storage point.

As I understand it, the batteries will discharge themselves down to around 30% (I believe) after 10 days (default) or however many day you have them set to discharge in the DJI Go app. This is for safe storage purposes. This is where I ,personally, leave them until ready to fly again. Then I just recharge to full again before heading out.

What about the battery in the controller, fully charged or half charged or 30% ?

The correct storage level for these lipos is 40 to 60 percent, not 30.

It means you did not set up the discharge timer for the batteries in the APP. I set it to 3 days and If I don't you use it it will discharge to 50% or 2 green lights.

I have the app set to discharge in 5 days, but now my three batteries have only 1green light showing, Is that OK or is the voltage too low for storing and should they be recharged to a certain level?

One light seems low. I have my discharge interval set to two days it's always two lights on my batteries when they discharge to their pre-programmed storage level.

Too low.  Charge again fully and let the self discharge take it down.

Videos I've seen show a Lithium-Ion battery in the controller.  Not near as critical as Lithium Polymer.

You can just charge it to 50-65% for storage, no problem. And if you like, you can also charge it to full, the battery will also do a self-discharge after a certain time. Remember, do a full discharge and full charge every 3 months to maintain the activity of the battery.
