Charging the Battery
NOTICE:
Charge only batteries that are cool to the
touch and are not damaged. Inspect the battery to
make sure it is not damaged e.g., swollen, bent, broken
or punctured.
CAUTION:
Only use chargers specifically
designed to charge the included Li-Ion-Fe battery.
Failure to do so could result in fire, causing injury or
property damage.
CAUTION:
Never exceed the recommended
charge rate.
Use only the included USB charger to charge the battery.
1. Connect the charger to a suitable USB power port.
The charger will work with most 5V mobile power
sources or smartphone chargers with at least 1 amp
of power output.
NOTICE:
Charging the battery with a USB power port
with less than 1 amp of power output can produce
heat.
2. Connect the charge lead to the battery, noting correct
polarity. Charging a fully discharged battery takes
approximately 60–90 minutes. Charge times may vary
depending on the power source.
3. Remove the battery from the charger when the
charging cycle is complete.
4. Remove the charger from the power supply.
CAUTION:
Once charging is complete,
immediately remove the battery. Never
leave a battery connected to the charger.

Charging Warnings
CAUTION:
All instructions and warnings must
be followed exactly. Mishandling of Li-Ion-Fe
batteries can result in a fire, personal injury and/or
property damage.
• NEVER LEAVE CHARGING BATTERIES
UNATTENDED.
• NEVER CHARGE BATTERIES OVERNIGHT.
• By handling, charging or using the included Li-Ion-Fe
battery, you assume all risks associated with lithium
batteries.
• If at any time the battery begins to balloon or swell,
discontinue use immediately. If charging or discharging,
discontinue and disconnect. Continuing to use, charge
or discharge a battery that is ballooning or swelling can
result in fire.
• Always store the battery at room temperature in a dry
area for best results.
• Always transport or temporarily store the battery in a
temperature range of 40–120º F (5–49° C).
• Do not store battery or model in a car or direct sunlight. If
stored in a hot car, the battery can be damaged or even
catch fire.
• Always charge batteries away from flammable materials.
• Always inspect the battery before charging.
• Always disconnect the battery after charging, and let the
charger cool between charges.
• Always constantly monitor the temperature of the battery
pack while charging.
• ONLY USE A CHARGER SPECIFICALLY DESIGNED
TO CHARGE LI-ION-FE BATTERIES. Failure to charge
the battery with a compatible charger may cause a fire
resulting in personal injury and/or property damage.
• Never discharge Li-Ion-Fe cells to below 3V under load.
• Never cover warning labels with hook and loop strips.
• Never charge batteries outside recommended levels.
• Never charge damaged batteries.
• Never attempt to dismantle or alter the charger.
• Never allow minors to charge battery packs.
• Never charge batteries in extremely hot or cold places
(recommended between 40–120° F or [5–49° C]) or place
in direct sunlight.
Low Voltage Cutoff (LVC)
Discharging a Li-Ion-Fe battery below 3V per cell may
damage the 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 will be reduced significantly, showing
that the battery has reached the minimum LVC threshold.
The ESC is programmed to allow enough battery power
to return to shore, at no more than ¼ throttle.
Disconnect and remove the Li-Ion-Fe battery from the
boat after use to prevent trickle discharge. Charge your
Li-Ion-Fe 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-Ion-Fe Cell Voltage Checker
(EFLA111, sold separately).
