    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.

    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
