SUPULSE 2 Pack LiPo Battery Checker - RC 1-8S Battery Tester Monitor Low Voltage Buzzer Alarm with LED Indicator
This checker will work on almost any 1-8S lipo battery. It reads individual cell voltages, and whole pack voltage.
SUPULSE Lipo Battery Low Voltage Tester Checker1S-8S Buzzer Alarm with LED Indicator for RC Helicopter for RC Drone/Helicopter/Boat/Plane.
There is also a low voltage alarm that will sound when the pack gets too low. The alarm voltage can be set by pressing the button on top of the unit. The voltage the alarm will sound is adjustable between individual cell voltages of 2.7v and 3.8v in .1v increments (3.3v is the default). It can be used in the model as an alarm, or on the bench as a voltage checker. A very handy tool to help prevent the over discharging of lipo batteries.
Upgraded version with plastic hull to protect this lipo battery low voltage checker alarm.

Works great on my RC Boat. Appreciate the alarm points you can set for low battery voltage.

Checks battery voltage as it should and it's small.

Does what it is supposed to do and seems to be accurate. I would recommend this product!

These are easy to use, and the alarm is very effective. They are not easy to read out in the sunlight, though. You have to shield the sun to see it well. That's not a big deal. However, I had them set to go off at 3.4 volts, and they did. But when I hooked the batteries up to my charger later, they were all reading 3.6-3.7 volts. So, that makes me think maybe these aren't exactly accurate, but I'm glad that if they are off it's that the battery is more charged than it reads rather than less charged. So, I'll probably just turn them down to 3.2-3.3 volts and see what they read next time.

Using this to monitor my LiPo batteries when draining them before storage. I use an automotive turn signal bulb to drain my charged LiPos to bring them down to a safe voltage for storing them as my charger doesn't have that functionality built in. While doing this, I want to make sure I don't inadvertently bring the batteries too far below the safe low voltage. So, I set the alarm at 3.7V and connect the bulb to the battery pack. Once the alarm goes off, I disconnect the pack and put it away. The only downside I've found to these alarms is that they aren't accurate and are off by 0.1 ~ 0.2V on the safe side. So, the alarm set at 3.7V goes off when the actual voltage is at or above 3.8V per cell which actually is preferable and isn't a problem for my use case.As others have stated, it is very loud. The case simply separates into 2 halves and the actual circuit board pops right out. I may at some point disconnect one of the alarm speakers or add some padding to soften the noise.

The alarm was too loud to use inside because it beeps like a smoke alarm every time you use it.It’s easy to open it up, break the speakers and close the case.When it’s quiet, if that’s what you want , it works great.

I wanted a device that would enable quick checking on the status of my collection of LiPo batteries... this performs that function very well. It's simple, accurate, and intuitive. Nothing more to ask.
