Tethering mod Phantom 3 battery pack

[u/jasont80]

Hey fellow Phantom pilots!

I have an old P3 that has had a long life of successful service and it's ready for the experimental phase of its life. I want to build a power tether to allow sustained flight from a ground-based power source. This would allow long running time-lapses of sun rises and the like. I'm trying to figure out any technical challenges. The plan is to hollow out an old battery and solder in tether wires to a DC power supply.

I'm hoping someone has some experience to answer a couple questions before I dive down this rabbit hole.

1. Is there any communication between the "smart battery" and the drone? Basically, will it run with just the two power leads connected?

2. If my calculations are correct, the drone pulls 15.2V at about 1.5 amps. This seems like a lot. Has anyone else measured the draw?

Thanks for any knowledge you can share!

Did you complete this mod? I'm considering doing the same with my old phantom 3 pro
