I use the 3000 mah 4s pack. When he starts pika it means that I still have 20 seconds of flight. Very useful. Good price and quality

Very good, small, LEDs are bright and buzzer loud. Wired into balance port of Lipo. Beware soldering iron too hot and melting connector/ changing pin alignment.

Description is missing the included blue and red leds, which was a good surprise for me.
1) Plug the monitor to your pack : Beeps, blue light flashing, then shine.
2) Battery > 3.7V x N ( Elements ) : blue light shines
3) 3.7 x N < Battery > 3.4V x N : blue light flashs
4) 3.4 x N < Battery > 3.3V x N : red light shines
5) Battery < 3.3V x N : red light flash buzzer

Excellent product
