I did a slow discharge of a P3P battery today by plugging the battery into the P3, turning it on, and just letting it sit next to me on the table top while I played with the camera settings (no motors spinning).  At one point, I picked up the P3 and noticed it was really hot.  The two hottest spots were the top of the shell under the dji logo, and the VPS sensor - I almost couldn't keep my hand on the VPS sensor it was so hot.  It never gets that hot while flying - even after 4 batteries non-stop.

Just curious, is that normal?  I got thinking that maybe when flying the wind helps keeps it cool, and that today, it was just sitting stationary while turned on for maybe 45 minutes or so.

> P3P
> iPad Mini 2 wifi/cellular
> All current firmware
> IMU calibrated successfully recently on flat surface using spirit level
> VPS has never been turned on - confirmed cause I looked at it while playing with the camera
> Everything stock
> One of the lucky birds - no issues.

Yes, they get hot even sitting idle, while turned on.
Perhaps more so, if the motors aren't armed, the Phantom 3 battery will get hot while discharging.
I noticed this same phenomena,  while merely playing within the SIM program.
I place my running Phantom 3 Pro' upon a cooling fan now, to help it stay cooler, while engaged.

Thanks for confirming.  I knew that spare cooling fan in the garage would come in handy someday.

OMG ... you never saw that video of the fisherman on the end of a pier getting pissed off at an Inspire buzzing about, and literally casting his line right at the Inspire and hooking it?

Someone find the link and reply.  lol

I also place my 100w charger on the fan, while charging my four batteries.
Heck, I even place my radio controller on the fan while it's charging.

If it gets warm, I chill it...  
I must cool my batteries down before charging them too, but I let them cool off, on their own.
