    Контроллер покупался для аккумулятора квадрокоптера и контроля его напряжения, по прямому назначению пока не использовался, но проверен все работает сигнал громкий. Доставка быстрая, упаковка хорошая.

    Small and very practical product in the field, may not be 100% accurate but do the job. Give the voltage of each cell and the full voltage, we can also set a mini alarm

    Works great. I'm not using it on a DIY drone, only to check my batteries, so I've unsoldered the two buzzers to preserve my ears, because even with only one active it makes very loud beeps each time you connect a battery.

    it works fine thank you , I have tested the unit with 1 cell battery as you can see . ( please note ) the low alarm buzzer sound ONLY works with 2 cells battery or more it doesn't work with 1 cell battery , but the voltage tester works fine with 1 cell batteries .

    Сигнализирует о низком заряде батареи. удобно проверять на сколько заряжены батареи или разряжены

    Marca primero la tensión de la batería y luego una por una la tensión de cada celda, se puede ajustar la tensión a la que se quiere que avise (pita con buen sonido) en los siguientes saltos: OFF-2,70v-2,80v-2,90v-3,00v-3,10v-3,20v-3,30v-3,40v-3,50v-3,60v-3,70v y 3,80v First check the voltage of the battery and then one by one the voltage of each cell, you can adjust the voltage to which you want to warn (beeps with good sound) in the following jumps: OFF-2.70v-2.80v-2.90v-3.00v-3.10v-3.20v-3.30v-3.40v-3.50v-3.60v-3.70v and 3.80v

    The device works fine, with an audible + visual alert when connecting. Weight is about 11g, so no overload expected on the RC aircraft. Not tested in flight so far and I also did not try to change the setting, so no feedback on this aspect. A weak point is that nothing prevents wrong connection (e.g. reverse polarity). This might be to allow for various load balance connector types, but seen the absence of any user guide, it is advised to take care of connecting exactly as shown in the attached picture.

    works perfectly, it shows voltage for each cell plus for all together. By pressing the button you can set the lower voltage when buzzer should peep, between 2.70-3.80 V or turn it off.
