My Feedback: (2)

As far as battery monitors, I use one of these in my planes. This is an audio alarm. Every time I turn it on it reports the pack voltage by a beep sequence. If a 4 cell pack falls below 4.6V or a 5 cell pack falls below 5.75, it let's me know. When I test my servos before a flight, if the voltage drops below these points it complains. If I am in the air and voltage drops below that level I can hear if the plane is not too far away too. In that respect it is better than a visual meter.

On a 72 mhz receiver this is also a lost model alarm that will help me find the plane in the woods. Handy device if you miss judge your energy.
