Low Voltage Cutoff (LVC)
The factory default setting for the LVC in the ESC included
with your boat is set at 3.2V per cell. Discharging a Li-Po
battery below 3V per cell may damage your battery. The
included ESC protects the boat battery from over-discharge
using Low Voltage Cutoff (LVC). Before the battery charge
decreases too much, LVC removes power supplied to the
motor.
The boat drastically slows or stops completely once LVC is
activated. Releasing the throttle and reapplying it will provide
a limited amount of power to safely return the boat to shore.
Once LVC has been activated, the ESC status light will fl ash
red continuously indicating that the ESC is in LVC mode.
Electronic Speed Control (ESC)
Programming
STEP 1: Enter Program Mode
1. Power on the transmitter and set the throttle to full.
2. Connect the battery pack to the ESC. After 2 seconds,
the ESC will beep twice.
3. Wait 5 seconds and the ESC will emit a musical tone.
STEP 2: Select Programmable Item
The ESC will emit four groups of beeps in a loop.
Move the throttle to neutral within 3 seconds of the tone
matching the item you want to select.

ESC Programming Procedure
Programming can be accomplished using the Dynamite ® LED Program Card (DYNS3005, sold separately) or via the trans-
mitter. Please refer to your DYNM3875 manual for transmitter programming instructions.

Possible Cause
Throttle channel is reversed

Boat squeals or makes a high pitch sound
when applying power to motors
NOTICE: Repeated operation to LVC will damage the
battery.
LVC can activate prematurely if you use (1) low C-rated
batteries or (2) old, worn, and/or weak batteries. The aver-
age run time—using the recommended batteries (DYN-
B3810EC or DYNB3811EC)—is between 3–4 minutes
at non-stop, open throttle. Limited run time may indicate
worn or weak batteries.
Tip: If you've installed freshly charged batteries, and LVC
activates within the fi rst minute of operation, replace your
worn or weak batteries with the recommended batteries.
Tip: Monitor your boat battery's voltage before and after
boating by using a Li-Po Cell Voltage Checker (EFLA111,
sold separately).
STEP 3: Set Item Value
After selecting a programmable item, you will hear several
tones in a loop.
1. Move the throttle to full to select the value matching the
tone. The ESC will emit an alternating tone to indicate
selection.
2. Keep the throttle in full to return to Step 2 and continue
item selection. Move the throttle to the neutral within 2
seconds to exit the Program Mode.
STEP 4: Exit Program Mode
1. In Step 3, after hearing the alternating tone, move the
throttle to neutral within 2 seconds.
