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)
3.3v is a bit low... As a safety feature fine, but you would want to think about landing your aircraft before reaching 3.3v. Does anybody know if you can buy one of these that beeps at around 3.5v - 3.6v?
I want to use in an FPV plane (I will hear the alarm through my camera mic) and I want it to beep when I have enough juice left to turn around and fly a couple of km home... at 3.3v it would probably be too late.
I realise an OSD with current sensor is a solution but this is a very simple set up and i want to keep it simple and not add an OSD. thanks
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.
