Just curious, is the battery the same between all 3 phantom models?  Reason I ask, thinking of buying another battery for my P3P.  However, saw the new prices of the Phantom standard, and thought if the batteries are interchangeable, might buy the phantom standard to have a drone the kids can fly with me.  I'm guessing they are different batteries, but couldn't find model/specs on the battery itself between the standard and professional model.

Thanks for any input you have!

I think all the P3 models take the same battery

Yes all Phantom 3 versions use the same battery.
