will be reduced 50%. Please replace the battery pack as soon as possible.
a) Warning! If you ignore the low voltage cutoff phenomenon and keep running, the battery pack will be damaged!
b) How to calculate the cutoff threshold of a whole battery pack:
The cutoff threshold of a battery pack = The threshold of each cell * cells number

4. Timing: Please select the most suitable timing value according to the motor you are just using. The correct timing
value makes the motor running smoothly. And generally, higher timing value brings out higher output power and
higher speed.

22.. Program the ESC with the Program Card
Program card is an optional equipment for boat ESC, it has 3 digital LEDs to show the programmable items and their
values, so the user interface is very friendly. It is quite easy for programming the ESC with this small equipment. Please
read the user manual of program card for more information.
