the alarm i used is when all of a sudden the heli wont fly, its cheap, effective, and works every time.
dont fly the darn thing till its not capable of lifting its own weight anymore. you dont need devices to tell you something your heli is already telling you.
your lipo is done when it seems like it just took a crap, you will notice a huge power loss within a period of about 20-30 seconds.
if you have enough power to only just hold a hover, its too far, i nearly ruined my lipo's doing that when i had a CP.
