So I have the 10 pin adapter cable so that I can use my P4 batteries to power my Osm+ in a pinch, my question is how long will they run for?  I assume they will last significantly longer than the Osmo battery but how much longer?  What about P4P batteries?  I am using the "high capacity" Osmo battery, but same questions for the "intelligent" battery.

532 minutes with Phantom 4 battery and 582 minutes with High Capacity battery.
Please note this is the maximum duration time that we tested when the gimbal keeps still with lowest video resolution. It will be reduced in actual operation.

Thankyou.

That is an impressive run time.
