Coming from Jeti, I’m new to Spirit Wave. I can’t figure out how to set an alarm for plugging in a battery that isn’t fully charged.
The alarm should activate when Motor Hold is on and the voltage is below a certain value. During flight, the alarm should remain silent.

Hello,
checking you battery before flight is much better then to check it by program - take some battery checker...they are not expensive -
That would be my recommendation for your safety.

Hello,

you can set Warning in Alarm menu for ESC - Battery Volage.
Then set voltage when it should call the alarm. Lastly you need to set activation during Power up.

This will check the battery when model is plugged in, not after.

Hi ZeXx86
That’s what I initially did, but it didn’t trigger the alarm — and it still doesn’t (please have a look at the video).
Maybe it takes a little time for the voltage reading to reach the Wave, and the time of "During startup" too short, so the alarm isn’t activated.
With Jeti, there was a workaround: the voltage alarm was triggered 10 seconds after plugging in.

Hello,

you are right this could be the case. Could you let me know what ESC you are using?
I believe we can sort it quickly.

Sorry for not mentioning, it's a Yge Aurelius 105. Maybe "During startup" should be longer, maybe 15 seconds or user-defined per alarm.
