Hobbywing say to set cell count manually for odd numbers of cells . The ESC will sometimes think 3 cell is 4 cell and set Low Voltage Cutoff to suit . You take off fine then LVC kicks in . It could also trigger an Over Voltage Protection in a 3S ESC if it thinks it has 4S hooked up .
I get 3 beeps on 3s and 2 on 2s so I guess it's working properly as far as recognizing the cell count.
