A hearty 'thank you' to DJI for their quick handling and out-of-warranty support of my Ph4 transmitter.  In stark contrast to the negativity in the random internet blogs, you guys came through.  I'm a fan.

Thanks for your kind words to our customer service, which give us confidence to keep moving, hope you enjoy flying the drone.

Can a mavic 2 transmitter be used for a phantom 4 pro?  I have a phantom 4 pro that the transmitter suddenly won't hold more than 1 dot of charge.  If I can't use the Mavic transmitter someone gave me, where should I buy a new battery for the Phantom 4 pro transmitter?  I saw a utube video once about how to replace it.

2 of my 3 phantom 4 pro drone batteries are dead, one won't hold more than one dot of charge and the other is completely dead, no lights, won't charge.  Can these be fixed or are they ready for the garbage?

what are primary differences between the mavic 2 and phantom 4 pro?

Thanks, Sloane
