Note6: Because the normal voltage of each Lipo cell varies from 2.6V to 4.2V, it is quite difficult to calculate the cells
number of a discharged Lipo battery pack. If it is calculated incorrectly, the Low Voltage Cutoff Protection function
may work abnormally, so the option
“Auto Calculate” is only available for 2s, 4s and 6s Lipo. If the voltage of the
battery pack is lower than 8.8V, it is judged as a 2s Lipo; If the voltage is between 8.8V to 17.6V, it is judged as a 4s
Lipo; If the voltage is higher than 17.6V, it is judged as a 6S Lipo. So in order to make the Low Voltage Cutoff
Protection function always works correctly, we strongly suggest setting the
“Lipo Cells” item manually.
2. Programmable Values
2.1. Running Mode: With “Forward Only with Brake” mode, the car can go forward and brake, but cannot go
backward, this mode is suitable for competition; “Forward/Reverse with Brake” mode provides backward function,
which is suitable for daily training.
Note:
“Forward/Reverse with Brake” mode uses “Double-click” method to make the car go backward. When
you move the throttle stick from forward zone to backward zone for the first time (The 1
st “click”), the ESC begins to
brake the motor, the motor speeds down but it is still running, not completely stopped, so the backward action is NOT
happened immediately. When the throttle stick is moved to the backward zone again (The 2
nd “click”), if the motor
speed is slowed down to zero (i.e. stopped), the backward action will happen. The “Double-Click” method can
prevent mistakenly reversing action when the brake function is frequently used in steering.
By the way, in the process of braking or reversing, if the throttle stick is moved to forward zone, the motor will run
forward at once.
“Forward/Reverse” mode uses “Single-click” method to make the car go backward. When you move the
throttle stick from forward zone to backward zone, the car will go backward immediately. This mode is usually used
for the Rock Crawler.
2.2. Drag Brake Force: Set the amount of drag brake applied at neutral throttle to simulate the slight braking effect of
a neutral brushed motor while coasting.
2.3. Low Voltage Cut-Off: The function prevents the lithium battery pack from over discharging. The ESC detects the
battery ’s voltage at any time, if the voltage is lower than the threshold for 2 seconds, the output power will be cut off,
and the red LED flashes in such a way:
“☆-☆-, ☆-☆-, ☆-☆-”.
There are 6 preset options for this item. You can customize the cutoff threshold by using a LCD program box
(optional equipment) to trim it with a step of 0.1V, so it will be more suitable for all kinds of batteries (NiMH, NiCd,
Li-ion, Lipo, LFP,etc). Please always keep in mind that the customized value is not for each cell, it is for the
WHOLE battery pack.
2.4. Start Mode (Also called “Punch”): Select from “Level1” to “Level9” as your like, Level1 has a very soft start
effect, while level9 has a very aggressive start effect. From Level1 to Level9, the start force is increasing. Please
note that if you choose
“Level7” to “Level9” mode, you must use good quality battery pack with powerful discharge
ability, otherwise these modes cannot get the burst start effect as you want. If the motor cannot run smoothly (the
