the fact that this can be simple to install on to the battery, how do you guys secure the alarm to prevent it falling off when u crash?

Hey I just bought some 3s lipo batteries from here along with a lipo alarm for my airsoft gun, and whenever I have the battery plugged in and the lipo alarm plugged in too, it beeps every few times I shoot but the alarm's lights stay green

don't worry, it simply means that the battery's voltage dripped when u shot, but picked up again.

Yes, one or more of the cells in your lipo battery goes below the voltage threshold for warning when your airsoft gun puts load on the battery. A bit strange in my opinion, but i have no idea what kind of power requirement airsoft guns have.

I think you need to pick up a higher discharge rating lipo. if you continue using that lipo it may end up destroying your lipo.

Very loud ear piercing sound that is easily heard, however i have not tested it out yet in a quad or similar but im quite sure you would hear it if not to far away and possible even at some smaller distance.

Just when the battery pack is connected it beeps for about a 1 seconds so be prepared for that and green lights come on that show which batteries are connected. If a battery voltage goes down to under about 3.3V it starts to beep at an interval off 0.5 sec on and 0.5 sec off (i would like it to be on constant but oh well, might be able to change some components to do so) and the same led that correspond to that battery blinks red at the same interval and the green corresponding led turns off completely at this point.

When the voltage goes up on that battery to over about 3.3V the beep stop and the green led goes on and the red stop to the next time it goes under again.

Nothing really to complane about exept this interval thing. I would absolutely recommend it but i havent flown with it yet though to see if it could be heard with motors on but im quite sure you would even at a little smaller distance.

I bought two of these. This is a great product. I tried with the alarm is loud and sounds very good from a distance at least 50 meters. Now I am calm about my batteries and know when to stop. I changed the old NiCd batteries on my drill and put lithium polymer 3s now works perfectly and alarm tells when to stop. I strongly recommend taze alarm.

I use this simple and inexpensive item on my own Multi-rotor craft. The LEDs are a great visual indication of battery voltage and the loud Piezo buzzer lets me know when its time to land with a safe amount of voltage in the pack - Ben
