Anyone have experience with this discharger? I just picked one up and an RDX2 800.
I'm only using the phone app so maybe more info when using the PC app.
Anyway.... Here are some app screenshots if there is any interest. I'll keep the thread updated if anything interesting comes up or anyone wants to see a particular feature.

What’s the mobile app called, and do you need a cable connection or is it wireless?

Hitec Linkpower X
The charger I have is Bluetooth so no cable needed. When I try the PC I'll let you know how that connects.

Quick updates.... I could not get it to connect to PC through USB-C, and I used the tire warmer output on the RDX2 800. It was easy and efficient.

Try a different USB cable, not all USB-C are capable of data transmission so it needs to be a high quality one.
