    Is there any way to get a low voltage warning with one of these http://tinyurl.com/qec38vc when I use the balance plug for FPV and the aux-power for gimbal? BTW, is there any way to use the phantom built in speaker as an low voltage alarm?

    Are you saying that you're using a separate power source for your gimbal, rather than it being powered by the Phantom?

    I think your best bet would be to split the aux power lead to run both the gimbal and FPV, leaving the balance tap on the battery free for the voltage meter. Do you have any connectors on your aux power lead now or is it just spliced directly to the FPV wiring?

    No, it is connected to the phantoms auxiliary power.

    OK. The gimbal is spliced directly to the aux wires. However the balance plug connector on the FPV had a power surge protection. If I connect it to the aux, I will lose that protection. But maybe it is redundant..?

    Pretty much. The Aux lead is run of the Phantom's main board which contains a PMU so you should be safe w/o the extra surge protection (I'm assuming fatshark?). Many people have P1's with Immersion/Fatshark Tx's run straight off the aux lead in conjunction with the gimbal.
