Simple to use Lipoly low voltage alarm that is small and light for on board use, plug's into balance lead for detecting low voltage on individual cells. A loud alarm will sound and LED will change from Green to Red if any individual cell drops to 3.3v or below.
Spec. Lipoly Range: 2s~4s Size: 38x25x11mm Weight: 7g Voltage Accuracy: 0.03v Low Voltage Alarm Threshold: 3.3v (per cell)
Make sure the ground line (black one ) lines up to the correct pins. I am sure you have lined the correct wire up but I have even forgot that before. They are really cheap so manufactures do have a failure rate. You might have just blown a diode or something cheap. I would advise buy another one. Well why not just buy couple more as they are so useful. I have one on every model I fly. They are so loud and even though they are cheap they do save your model from going into a no power landing. Good Luck
I used it for once fully. At the end of first fly when i was landing ,which landing was little hard, the alarm released from battry and olso plane then it trown away from plane and broken. It was interesitng. Now just leds are working when battery cells low, there is no sound so no buzzer... I dindt understand anything. It was sily
Same happen to me .Now just leds are working when battery cells low, there is no sound so no buzzer
1 thumbs up!
4 Stück gekauft, wurden vom Zoll beschlagnahmt weil das CE-Zeichen fehlt. HobbyKing leistet keinen Ersatz und fühlt sich nicht zuständig.

I love this smal alarm system. Easy to fit and very safe. After connetion, it check every cell of your Lipo and the horn will be activated for a second. It is very loud and a nice working tool for more saftey.
