You could always us the old school way, fly with a cell checker that beeps when it's time to land.
I'm liking this idea. Need to learn more about it.
They are the best, last forever and nice and loud
Just bought a couple. I'm in the "learn how to take care of your batteries" learning curve at the present.
Here are some pictures that show my current settings. The battery connected is at 12 volts. The voltage indicated in the telemetry screen is a set voltage from the offset field or something like that. I don't think my ER6 is sending the voltage. I checked in the receiver and the "Force telemetry off on this receiver" is not selected. I'm sure I'm making this harder than it should be. Addendum: I just thought to test my ER5. It is sending the correct voltage. So It's something wrong with my ER6 set up. Hmm, that's progress.View attachment 258117
Basically, while the radio link is active, you go to the model settings telemetry screen and "Discover new" the telemetry sensors that the RX is setting. Once you have those established. You can set up alerts or use a LUA script that monitors the telemetry and gives shout outs.

Read the instructions on the back of the cell checker, they show how to change when the beeper goes off. I fly down to about 3.0v per cell, the pack will recover to 3.5v per cell after 15 minutes of so.
I do a combination of Flight Timer, Radio Telemetry, OSD (if FPV), plane feel, and plug-in beepers. Depends on the plane, battery pack, RX, and time to fly. If the plane starts feeling laggy or the motor isn't spinning up like it did at the start of the flight, I bring it in ASAP.
There is no telemetry antenna to plug in. There is a battery monitor plug that needs to be wired to your battery to get voltage. Without that hooked up, you can see the RX voltage from the ESC/BEC but not the battery voltage.
Ah, I see. I looked through loads of videos and no one ever spoke that essential piece of information. That seems like a pain in the butt. No wonder people look to other ways to deal with battery levels. With my timer set up and the battery checker alarms, I won't really need to do this, but my curiosity never leaves me alone. With what you told me I was able to do a better search and found this video that shows what you are talking about. For the record:
