Low Voltage Cutoff (LVC)
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. Power to
the motor pulses, showing that some battery power is
reserved for boat control and safe landing.
Disconnect and remove the Li-Po battery from the boat
after use to prevent trickle discharge. Charge your Li-Po
battery to about half capacity before storage. During
storage, make sure the battery charge does not fall below
3V per cell. LVC does not prevent the battery from over-
discharge during storage.
NOTICE: Repeated operation to LVC will damage the
battery.
Tip: Monitor your boat battery's voltage before and
after boating by using a Li-Po Cell Voltage Checker
(DYN4071, sold separately).
Battery Chemistry
The ESC comes from the factory in Li-Po Mode. To
change battery chemistry:
1. Keep the throttle at neutral and power ON the ESC.
2. Press and hold the Battery Chemistry Button on the
power switch for 3 seconds. The LED flashes the
current battery chemistry (red = Ni-MH or Ni-Cd,
green = Li-Po).
3. Continue holding the Battery Chemistry Button
for another 6 seconds. The ESC changes battery
chemistry and the LED flashes the new battery
chemistry.
4. Power OFF the ESC. The ESC saves the setting until
it is changed.

Getting Started
1. Power on the transmitter. Ensure the throttle is not
reversed and the throttle trim is neutral.
2. Connect the battery to the ESC.
3. Keep the throttle at neutral and power ON the ESC.
The ESC automatically calibrates the throttle range
after 3 seconds. A beep will sound, indicating battery
chemistry and cell count:
• 1 beep: Ni-MH or Ni-Cd
• 2 beeps: 2S Li-Po
• 3 beeps: 3S Li-Po
One short beep will sound when the ESC is ready
to run.
4. Test the transmitter’s control of the boat with the
boat on the display stand.
