Alarm Voltage set to 3,4V
If the buzzer will start making noise during the flight - I land my Heli with approximate 3,65V/cell -(3s 2200mAH Lipo in a Beam E4 Flybarless Heli). Charging then again approximate 1900 mAh.
The buzzer is very very noisy - yow will hear it without problems up to 60-70 m disctance! Great value for approximate only €6,- incl. shipping from HK to Germany!!!
Beware, there're 2 versions of this. The original one with Qinlon buzzer.. Extremely loud. And it will take voltage SAG into consideration. During sag, it will buzz.. Once you let go throttle, voltage goes back up, it stops buzzing. This is the one you should get. The others... Won't stop buzzing even after voltage drop from sagging and it's not as accurate. The crap version also is not loud. You have the crap version of the buzzer.
