Yes, if the GND lead doesn't have a potential over the other leads the alarm shuts off.

I have an application where this would be permanently mounted in a hard to get at location. I'd like to be able to leave it attached to the balance port between uses and not have it draw off the battery. Can I put a SPST switch in the balance plug ground lead to turn it off?

TURNIGY Plush 40amp Speed Controller PRODUCT ID: TR_P40A will be a good choice. But it will be better if you ask questions about the products in that products pages.

I need a device similar to this one, but that, instead of beeping and sounding would cut the power supply. There are any device that acts like that?

Usually we program ESC to setup the cut off voltage :)

I want to use it ti a very specific situation, and in this particular situation, there is no ESC!

Just take a relay and a variable resistor. dial in the voltage for witch you want to cut off the power with the resistor (using a multimeter) and the relay switches off the power.

Can any one tell me how loud this is? ie. Is it loud enough to hear if it was in a PEQ box on the side of my airsoft AEG? Thanks in advance

He only reference to the loudness I can give you is that I can hear the beeping sound even if the unit is inside a model plane at the distance of 40m and more.

You'll hear it. I have one mounted in a battery powered drill and it still can be heard with all the noises that drill produces

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.
