    I have just bought a 250 pro second hand and whenever I start flying I get a low voltage warning on the radio and the device starts beeping.

    If I land the device and wait a couple of seconds the alarm stops and I can fly it for a bit longer before it starts again.

    I have tried multiple batteries that I am sure are charged but get the same results.

    Any ideas?

    The batteries need replacing. They have exceeded their use by date. :)

    You need to check them with a LiPo checker. You will most likely find that at least 1 cell has gone bad.
