Overview
The Losi Xcelorin electronic speed control (ESC) is specifically designed for
operating Sensorless brushless motors. Featuring low on-resistance, enhanced
throttle response and strong brakes, this ESC has enough features to satisfy
the most demanding driver. The pre-installed high airflow fan attached to the
ESC heat sinks keep it cool and performing to the peak of its ability. In order to
maintain 100A continuous current draw, the Xcelorin ESC uses very high quality
electronics and the best MOSFET transistors available.
LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 4
A key feature is the three (3) stored settings within the ESC that are easily
recalled for convenient use. These stored settings are referred to as “profiles.”
These do not limit the functions of the ESC as you can easily use the included
Advanced Quick Programming Card (AQPC) to make changes to any desired
setting.
The Low Voltage Cutoff (LVC) is preset for NiMH batteries. For more
experienced users, it can be changed to support both 2-cell and 3-cell LiPo
batteries. Using the Advanced Quick Programming Card (AQPC), adjustments to
the ESC can be made quickly and simply.
The Xcelorin ESC has a feature within it to prevent the vehicle from going into
reverse before you have come to a complete stop. Once you have come to a
stop, release the throttle trigger to the neutral position. Once you have been at
neutral, push the trigger forward to engage reverse (if active). The ESC is also
programmed to prevent going directly from reverse drive to forward. The ESC
will have a short pause when changing from reverse to going forward to
prevent damage to the motor or drivetrain of your vehicle.

Throttle Limit – 60% of Full Throttle
Reverse Throttle Limit – 30%
** AQPC cannot change
NOTE: You must use the supplied Xcelorin Setup Software to access all
features of the ESC.

Overriding the Active Profile
There are three (3) saved profiles within the ESC that were previously
described. To override a setting within the active profile, select a saved profile
that resembles your needs, or make further changes to the current profile.
Review the AQPC and set jumpers to your choice. You must make a choice for
each area of the AQPC, Cutoff Voltage, Brake, Drag Brake, Throttle Limit,
Reverse Throttle Limit and Motor Timing.
For example if you have the ESC active profile set to Profile #3 (Default) and
would like a little more speed but would like nothing else changed, place the
jumpers on the following choices.
Cutoff Voltage - NiMH
Brake - 80%
LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 8
Drag Brake – 40%
Throttle Limit – 80% of Full Throttle (was 60%)
Reverse Speed – 50%
Motor Timing - Low
Then follow the instructions for using the Quick Programming Card. You can
change one setting at a time or any combination. Making the above change is
ONLY overriding the active profile. At any time, you can reset the ESC to
profile #3 and the active profile is returned to the original profile #3 settings.
Selecting profiles
Notice that Profile #3 is set from the factory as the DEFAULT.
1. Turn the Transmitter on.
2. Turn the vehicle on.
3. With the ESC turned on and ready for operation, press & hold the setup
button until both the Yellow and Blue LEDs flash.
4. Release setup button.
5. The status LEDs flash to indicate the current profile setting.
LED status for each Profile below:
LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 9
Profile 1 Yellow and Blue LED flash
Profile 2 Yellow, Blue and Green LED flash
Profile 3 Yellow, Blue, Green and Red Flash (default setting)
6. To make a change, quickly press the setup button, which will advance you to
the next profile.9
M
7. When you are finished, press and hold the setup button for 2 seconds, the
four status LEDs will scroll and the new selection will be stored to the active
memory of the ESC.
8. If you do not press the setup button within 15 seconds, the four status LEDs
will scroll to indicate you are exiting programming. The ESC will return to
neutral and be ready for use without any change.

Modifying the ACTIVE profile
The Xcelorin Advanced Quick Programming Card (AQPC) is used to make all
adjustments to the active profile in your ESC. Any ACTIVE profile can be
modified.
