When connected you hear a short and loud beep as a test. Afterward green lights corresponding to the state of charge. At last a long beep as a warning to stop operating.

Good to attach to aircraft so I don't knacker my battery. Makes a loud noise so in no doubt it is time to land.

Just got this in today. It works great and does what it says in the description. This is going to come in handy, now i won't have to just rely on setting a timer every time.
