Can anyone tell me if the P4 and P4P battery works on Phantom Advanced?

All P4 series batteries are compatible and can be used in all P4 models. Only difference was that the first batteries produced for the P4 (before P4 Pro & P4 Advanced) had a slightly lower capacity.

Hello and good day. Thank you for reaching out and for the inquiry. Aardvark is correct on post #2. The intelligent flight battery of the DJI Phantom 4 Pro is compatible with the DJI Phantom 4 Advanced. If you have any other inquiries or concern with DJI. Please feel free to post it here at DJI Forum. We are here to help and support you. Thank you.
