Low voltage buzzer

Item as listed, great product for a great price accurate readings & very loud. Highly recommend.

Loud and the protected pins are a nice safety feature.

This beeper is plenty loud enough to bury inside a foam R/C plane and still be heard from a good distance while flying.
I also found the that because the pins are inside the cover, there is much less danger of the pins puncturing the LiPo battery in a crash. I now feel safe to carry a beeper in my LiPo bag so I know I won't forget it.

Works like a champ!

Small, light, solid. Works exactly as it should.

Great Device

It works well, I use it on a 5.8 ground station to warn me if the battery is getting low.

Thanks for your review, happy to know it works for your project.
