4 • VELINEON POWER SYSTEM
Safety Precautions
VXL-3s Electronic Speed Control
• Water and Electronics Do Not Mix: Your VXL-3s
brushless power system is waterproof for use in mud,
snow, puddles and other wet conditions. Make certain
the other components of your model are waterproof
or have sufficient water resistance before driving in
wet conditions.
• Disconnect the Batteries: Always disconnect the battery
pack from the speed control when not in use.
• Transmitter on First: Switch on your transmitter first
before switching on the speed control to prevent
runaways and erratic performance.
• Don’t Get Burned: The heat sink can get extremely hot, so
be careful not to touch it until it is cool. Supply adequate
airflow for cooling.
• Use Stock Connectors: If you decide to change the battery
or motor connectors, only change one battery
or motor connector at a time. This will prevent damage from
accidentally mis-wiring the speed control. Please note that
modified speed controls can be subject to a rewiring fee
when returned for service. Removing the battery connector
on the speed control or using the
same-gender connectors on the speed control will void the
product’s warranty.
• Insulate the Wires: Always insulate exposed or damaged
wiring with heat shrink tubing to prevent short circuits.
Batteries and Battery Charging
The Velineon Power System uses rechargeable batteries
that must be handled with care for safety and long battery
life. Make sure to read and follow all instructions and
precautions that were provided with your battery packs
and your charger. It is your responsibility to charge and care
for your battery backs properly. In addition to your battery
and charger instructions, here are some more tips to keep
in mind.
• Never leave batteries to charge unattended.
• Remove the batteries from the model while charging.
• Allow the battery packs to cool off between runs
(before charging).
• Always unplug the battery from the electronic speed
control when the model is not in use and when it is being
stored or transported.
• Do not use battery packs that have been damaged in
any way.
• Do not use battery packs that have damaged wiring,
exposed wiring, or a damaged connector.
• Children should have responsible adult supervision when
charging and handling batteries.
