Size Each Size: 4*2.5*1.1cm Each Weight: 9g Package 5PCS 1-8s Lipo Battery Voltage Tester ( 2in1 Battery Voltage Display and Low Voltage Buzzer Alarm ) Review: Impressive little battery checkers - I bought these battery testers after seeing them featured on a YouTube video by the TheRcSaylors. That video showed how they work and explained how they can save you much money by being able to monitor your LiPo batteries quickly and accurately. I've been using mine on several batteries since getting them. They are easy to use and do their intended job. They are small and don't weigh much at all, so can be used in a RC plane to tell when the battery is approaching the low voltage range that could damage the battery. The warning sound is quite loud, and will do the job. I highly recommend these little devices. Review: Must have. - Very happy with product. Works just like it says. Should have bought these a lone time ago. A must have for RC pilots. ## Features - 5PCS Lipo Battery Voltage Tester, Low Voltage Alarm Mode for 2-8S, Function of Checking Your Lipo Cells Voltage - Use for 1-8s Lipo/Li-ion/LiMn/Li-Fe,the Lipo Battery Meter Automatic Protects Against Reverse Connection,RC Low Voltage Buzzer Alarm,Battery Monitor Checker Tester - LED Voltage Display Function,Lipo Battery Voltage Tester Clearly Display the Value of Battery Cell Voltages, Total Voltages, Lowest Cell Voltage,Remaining Battery Capacity, and Low Voltage Alarm Funtion - Protect the Battery from Overcharging or Overdischarging, Test the working state of lithium battery - When the Voltage is Below the Set Value,the Battery Voltage Tester will Keep Buzzing with Red LED Light.the default Pre-set Value 3.3V.

This buzzer does NOT stop beeping once the cells recover, and it is *incredibly* frustrating and annoying. I have only tested 2 of them, but 2 of my 5 were set to 3.7v, dropped below that voltage on a punchout, and continued to beep all the way to the ground. When I checked, the beeper was still beeping, despite the batteries being 4.0v per cell on all 3 cells. **Q: Is the alarm loud enough to hear if plugged into you're RC airplanes 👂👂** A: Not if you are using a1S (3.7V) battery. 3S or more (11.1 or more) it is pretty loud. Although It does measure the 3.7Volts. If you look on YouTube (rcsaylors) he explains how it works. **Q: Is there an answer to 1S not working? Is there a fix?** A: Just tested mine with a 1s - works fine. I did have to make an adapter to make it work as my battery is off brand for my plane. Was easy to do and quick... Not sure why the OP is saying it won't work... **Q: Is there a place to drill or cut to sabotage the beeper and just go with the led?** A: take the busser off , ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive little battery checkers *by V***N on July 26, 2019* I bought these battery testers after seeing them featured on a YouTube video by the TheRcSaylors.
