In the Phantom 2 manual, DJI recommends completely discharging batteries every 20 charges. I don't see that in the Phantom 3 manual -- but, they do talk about completely discharging the battery for some reason.Is this necessary for the P3?

Yes, sir. And, you dug up an old threadPage 4 on the Intelligent Battery PDF (Phantom 3) you posted in another thread (Store battery | DJI Phantom Forum)
That's what I do. I take a 50 Watt 12 Volt halogen bulb and let it drain the battery. Make sure to monitor the voltage and verify the state-of-charge percentage to prevent over-draining.How you can discharge your Phantom battery? Can I use e.g. bulb and connect it to battery terminals?
Just charged the battery full.My battery has 35 cycles and it hasn't ever been calibrated.
I flew it down to 25% and left it powered without props.
I read that then let the battery die while ac powered.
It went to 0% and cells down to 3,3 volts.
Then I read that you shouldn't let it discharge below 8% or completely discharge until battery dies.
Waiting now battery to cool down and then charge to 100%.
Did I make a mistake when I discharged it completely down to 0%???

Yes - I think that's why the full discharge - to reset the counter which keeps track of the capacity which the charger puts into the battery from that known minimum level to fully charged. The reported capacity isn't updated in real time. I saw this when I had a battery fail 1 min into a flight - showed 96%. When I cycled it a couple of times, I noticed this lag. It's at least 30 seconds.Just charged the battery full.
I did put it in to AC to see did i kill it, but it seems good. All cells are @ 4.3 volts but dji go shows that batterys total capacity is "only" 4350mAh?? There is printed 4480mAh to the battery. It did show the same even before discharge so no change here.
When more and more cycles come and battery life gets worse does this total capacity decrease?
