lets try this again (posting)...This looks about the same, I don't think they are meant to track anything, just check lipo battery voltage and give an alarm once they drop below a certain pre-set voltage.
A loud alarm would be good enough I think but this is out of stock... any other options out there?
Interference with what? It's simple device that contains a speaker.
Sorry, not tec savy yet. I’ll order now, thank you much.
That's not my website. You'll need to contact the seller for shipping details.
