    Mr.
    Even thought I gave 5 star rating, the product description states that it takes 2-4s batteries however, the alarm can take only 2-3s batteries and not 4s batteries. The description should be changed. I ordered the product based on the description but failed to see that the photo is different. Usually items are ordered based on the description and not the photos. I will now have to try and sell these off to others.
    Suggestion
    The buzzer is loud enough

    Low Voltage Buzzer BB LED Annunciator for 2-4S from GearBesr.com
    Устройство очень легкое. Специально взвесил, 4 грамма. Размерами тоже порадовало. Миниатюрное. Подойдет тем, у кого ограничение по весу и размеру. К тому же пищалка очень громкая.

    LOUD Low Voltage Buzzer
    Really loud alarm. Sounds like a smoke detector. Giving enough time to land safely, and if the helicopter disappears from the field. You can find the basis of its sound. Now I'll allways find my Wltoys v912.
    Suggestion
    This would be lighter without LED lights

    Low voltage buzzer
    Works great as an alarm for low voltage on my rc boats so I can pull them back out of the water before battery runs critical and they get stranded

Q

Can I use it to test a LIPO Battery with 7,4 Volt and 20/25 Cells? If yes, since I use the battery to play with an Airsoft Electric Gun, can I hold this product attached to the battery when I'm using it (playing softair), so I'll be advised when the battery is too low to continue using it ?
