Battery Charger

Choose a charger designed to charge the recommended
(2) Spektrum 7.4V 5000mAh 2S 100C Smart Hardcase
LiPo Battery: IC5 (SPMX50002S100H5), or (2) Spektrum
11.1V 5000mAh 3S 100C Smart Hardcase LiPo Battery:
IC5 (SPMX50003S100H5)We recommend the Spektrum
Smart S2100 AC Charger, 2x100W (SPMXC1010). Refer
to your charger manual for charging instructions and
safety information.

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).

Getting Started

1. Power on the transmitter.
2. Connect the two batteries to the
EC5 ™ connectors on the ESC.
3. Power on the ESC switch. The ESC
arming tones will sound.
4. Test the transmitter's control of the
boat with the boat on the display
stand.
30 - INCH READY - TO - RUN BRUSHLESS BOAT
NOTICE: Never charge a battery in the boat or damage
may result.

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 fl ashes the cur-
rent battery chemistry (red = Ni-MH or Ni-Cd; green
= Li-Po).
3. Continue holding the Battery Chemistry Button for an-
other 6 seconds. The ESC changes battery chemistry
and the LED fl ashes the new battery chemistry.
4. Power OFF the ESC. The ESC saves the setting until it
is changed.
