    Lipo checker
    This 1S-8S Cell Checker with low voltage alarm features two loud alarms to notify you once your cells reach a user defined voltage. You can customize the alarm to sound at a voltage between 2.7v~3.8v per cell in 0.10v increments by pressing the setting mode button. This unit also features a handy built in LED display that will show the voltage of each cell followed by the overall voltage of the pack.Don’t risk your model by flying on depleted batteries, at this price piece of mind flying can't be any cheaper!

    Good - but alarm not working for 1S batteries
    Fine voltmeter for checking voltage of LiPo batteries. Easy to us*e and precise - if it is correctly set by manufacturer. Otherwise you need to calculate real voltage :( From my package 1 of 4 was 100% accurate, others shows from +/- 0.10 to +/- 0.50 but still can be used if you substract or add difference. Not very practicall to use these 3 innacurate testers, but still usefull if you know impropper tolerance they made. I use them to check voltage during charging to storage voltage value.
    Alarm does not work for 1S batteries. I think it is the way this things work because voltage on 1S is too low for speakers and the same is for all 4 testers in the pack. I don't have any 2S to check.

    Voltage indicated and alarm
    Sinice most quadcopter companies don't build their quadcopters with low voltage alarms, I purchased these so I don't have to worry about running out of power in mid-aire and or loosing my quadcopters. They work great because since they are adjustable, I set my alarms to 3.50 volts.
    Excellent. No negative comments.

    funzionano ma
    sono abbastanza accurati e si innestano facilmente. il buzzer funziona da 2s in su. classica modalità di funzionamento per l'allarme con pulsante.dopo un po di utilizzo 3 su 4 hanno iniziato a dare letture errate sula terza cella. gearbest ha rimborsato ottimo!
    si sono rotti in parte

    Удобное устройство
    Очень удобное устройство для контроля аккумуляторов без защиты. При понижении заданного порога напряжения начнет громко пищать (только для 2-8S). Есть возможность коррекции пределов напряжений под разные типы аккумуляторов.

    Gostei do produto
    Recomendo o produto, primeiro porque mede a voltagem com precisão, segundo é que o volume do alarme é bem alto, o que é melhor quando você esta utilizando num aeromodelo, helicóptero ou drone que vai longe de você. Quando as baterias chegarem a voltagem que você regulou ele toca o alarme e da tempo de retornar com o aeromodelo para perto de você.

    Perfecto para comprobar estado de lipos
    Es un dispositivo muy práctico para comprobar el estado de la lipo y además para ver si el cargador está actuando correctamente.Tiene una fiabilidad respecto a los datos de carga, adecuados para el tamaño y precio

    1 - 8S Lipo Battery Voltage Tester - Colormix
    Works perfectly on all my Lipos! It's loud enough to hear when your RC Car or Boat is running! Great Price!
