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)
This unit can only be plugged in before running your Rc correct.
If your storing your Rc overnight you have to disconnect from balance plug as the leds that are on will drain lipo ?
Bit of a pain when you have to take apart radio box etc or is there a better way.
Greg, the units and leds take around 60 mA of current. If you have a 2200 mAh lipo, so in a day and a half the lipo will be drained. The idea of this device is to plug it before you use your RC gear, and disconnect it after use. Otherwise, you also risk weaking up in the middle of the night, frightened by the loud noise of the buzzer :-)
Hey mark, the only thing you have to do is connect the battery balancer adaptor ( the small white) with the red wire on ( ), for example if you are using a 3s lipo leave 1 pin and connect starting from the second so you have 4 pins connected, if you are using 4s all pins are connected hope make sense.

Just plug it and wen it beep charge your batery very simple
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.
