Important Note: Lithium Ion baeries are more volale than the alkaline, NiCad and NiMH
baeries used in other RC applicaons. All instrucons and warnings must be followed exact-
ly to prevent possible personal injury or damage to property, including by re. By handling,
charging, or using the included Li-ion baery you assume all potenal risks. If you do not agree
with these condions, please return your complete product in new, unused condion to the
place of purchase immediately.
Important - Please read the following safety instrucons and warnings before handling,
charging, or using the included baery.
•You must charge you Li-ion baery in a safe area away from any ammable
materials.
• Never charge the Li-ion baery unaended at any me. When charging the
baery you should always remain in constant observaon of the baery to
monitor the process and react immediately to potenal problems you observe.
• Aer discharging the baery during running the boat you must allow it to cool to
ambient room temperature before aempng to recharge. Also, it is NOT recommend
ed that you completely discharge the baery before charging. It is safe to charge par
ally discharged baeries when using an appropriate Li-ion charge
• For charging the baery you must use only the included charger or a suitably
compable Li-ion baery charger. Failure to do so may result in a re causing
property damage and/or personal injury. DO NOT use a NiCad or NiMh charger to
charge your new Li-ion baery.
• If at any me during the charge or discharge process the baery begins to
“balloon” or swell, disconnue charging or discharging immediately! Quickly and
safely disconnect the baery before placing it in a safe, open area away from
ammable materials for observaon for at least 15 minutes. Connuing to charge
or discharge a baery that has started to “balloon” or swell can result in a re. Import
ant note: A baery that has “ballooned” or swollen even a small amount must be re
moved from service immediately and completely.
• Never discharge a Li-ion baery below 3V per cell.
• Always disconnect a baery from the ESC when the product is not in use.
• Avoid connually operang the baery to LVC (Low Voltage Cuto) as this could
result in damage to the baery.
• Store the baery parally charged (approximately 50% charged or 3.85V per cell)
at room temperature (approximately 68 to 77o Fahrenheit) in a dry area for best result
• When transporng or temporarily storing the baery, the temperature range
should be between 40 to 100o F. Do not store the baery or boat in a hot car or in
direct sunlight whenever possible or the baery could be damaged or even catch re.
• Li-ion cells should not be discharged to below 3.0V each. In the case of this 2-cell,
7.4V baery you should not allow the voltage to fall below 6.0V during operaon.
• Do not over-discharge the Li-ion baery, which could result in reduced power,
lower run mes or complete failure of the baery.
NOTE: The included ESC features a “so” LVC (Low Voltage Cuto) that smoothly reduces pow-
er to the motor (regardless of your throle posion) to let you know that the voltage to the
baery is near the 6.0V minimum and avoid damage to your baery.
