Hey Everyone,
With lipo batteries I am used to keeping the unloaded voltage per cell at 3.7 min and flying to around 3.3 or 3.4 v per cell min before landing.  With the Spark, I see a battery % instead of voltage so I am confused how it relates.  Is 30% remaining equivalent to 3.7v per cell and that is why the low battery warning comes on or is 0% 3.7v per cell?

I have seen a number of videos where people are flying the spark well below the 30% battery warning so I am just curious what the right thing to do for the batteries is.

Thanks,
John

I'm also curious. Coming from miniquads.

30% is about what I fly mine considering I used to run RC cars with lipo no less than 20% I would say is a safe zone.

I same too... which after fly battery levels is under 10% (the led 1 is blinking), and then i recharge the led 1 is on and the led 2 is blinking... is this the battery levels is more than 10%?

I'm going to continue doing this until someone from DJI verifies what the actual % means.  I see so many videos of people flying with even 10% left that I feel like I am short changing myself but I don't want to ruin the batteries.

Guys, please remember that we have "intelligent flight batteries". They switch off themselves before getting to a damaging low level. Theoretically you can always fly them until they switch off. But if you love your copter, you better return it back to you before it happens {:4_181:}

Intelligent or not i go by the voltages per cell. Dont really trust the software.....so 20 to 25% mark it is for me

I do not think, you will come close to 15 minutes flight time with 25% juice left. Even flying around in P only, for the max flight times it is more needed, to be in the one digit area there

I'm confused as well.  

What is the good percentage to stop flying at?
What % should a battery be stored at?
What % + Time will a battery go into Hibernation?
When should I charge my battery?
     - before flight if it's not in use often,
     - after every use? knowing it's not being used for a few days.

Good points, Sparky_17

Thinking on the DJI suggestion, to decharge the batts down to 5% for flights IN airplanes, I do think that DJI has set the % of the batteries to the "usable" range
Cause all I ever read about, mainly from smartphone batteries , down to 5% would stress the battery enormously.
And that would be intelligent, in my eyes.

And to OP, for the volt look in the app:
