    When connected you hear a short and loud beep as a test. Afterward green lights corresponding to the state of charge. At last a long beep as a warning to stop operating.

    Good to attach to aircraft so I don't knacker my battery. Makes a loud noise so in no doubt it is time to land.

    - Charge level alert (3.3v/Cell) is to low. 3.7v/Cell would be better for me. - On the other hand we have a good size (33mm x 19.6mm ), weight (4.5g) and a user friendly tool : Battery < 3.37v : the corresponding LED will flash red light quickly and beeps. 3.37v > Battery < 4.3v : the corresponding LED will adhere to the green, but no beep. Battery > 4.3v : the corresponding LED will be flashing red light slowly and beeps. Thanks

    Il prodotto è conforme alla descrizione: è molto piccolo e leggero e il cicalino (buzzer) è discretamente forte, sebbene sia singolo. Lo tengo attaccato col biadesivo al mio HUBSAN H501S per cadute accidentali e facilitare la ricerca e anche per controllare ad orecchio lo stato della batteria e ritornare al punto di partenza. Consigliato

    Just got this in today. It works great and does what it says in the description. This is going to come in handy, now i won't have to just rely on setting a timer every time.

    É o segundo que eu compro é fantástico a campainha para avisar quanto tempo você tem de bateria e funciona muito bem recomendo para quem faz voo ou pilota carro de controle remoto.

    Заказал 04,05 получил 20,05. Номер отслеживался. Индикатор работает, пищалка пищит, светодиоды горят

    This tiny buzzer is simply a must-have on your racing drone or just any flying rc model. It's super compact and super sturdy, even the pins are well protected against shock or fall damage, i've also crashed into water with my drone and this still worked perfectly after that (although it is NOT waterproof so do not submerge it on purpose). It connects to the balancer cable on your lipo (up to 3S due to the number of pins). As soon as you connect it you will hear a powerful "beep" that'll give you
