e.  The system will exit automatically and save the setting after nishing the desired item. You 
only  can  setup  one  item  at  a  time,  if  you  want  to  program  another  item  you  need  unplug  the 
battery and power on the ESC again.

1)

  For  Li-xx  packs-  number  of  cells  are  automatically  calculated  and  requires  no  user  input 

apart from dening the battery type. This ESC provides 3 setting options for the low voltage 
protection  threshold  ;  Low  (2.8V)/  Medium  (3.0V)/  High  (3.2V).  For  example  :  the  voltage 
cutoff options for an 11.1V/ 3 cell Li-Po pack would be 8.4V (Low)/ 9.0V(Med)/ 9.6V(High)

2)

  For  Ni-xx  packs-low  /  medium  /  high  cutoff  voltages  are  50%/60%/65%  of  the  initial 

voltage of the battery pack.. For example: A fully charged 6 cell NiMh pack's voltage is 1.44V 
x  6=8.64V,when  “LOW”  cutoff  voltage  is  set,  the  cutoff  voltage  is:  8.64V  x  50%=4.3V  and 
when “Medium” of “High” is set, the cutoff voltage is now 8.64V X 65%=5.61V.

4. Factory Setup Defaults:

a. Turn on your radio and set the throttle stick to top positon (100%)
b. Plug the battery pack into your controller
c. Wait for 2 seconds, you will hear 4 groups of two sets of fast beeps, after this you will hear 
four single beeps to indicate you have successfully entered the programming mode
d. When  you  hear  “—    —  —  —“  means  you  are  in  the  Factory  Setup  Defaults  menu,  please 
choose your desired value by pulling the throttle stick to the lowest position.
