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-Po 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 char-
gers 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 the Battery
CAUTION:
All instructions and warnings must be followed
exactly. Mishandling of Li-Po 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-Po 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-PO 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-Po 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.
Charging Warnings
Discharging a Li-Po 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-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 (EFLA111, sold separately).
