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.

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.

LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 10
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.

• 60% of full throttle

LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 12
Using the Quick Programming Card
With the AQPC in your hand and the back facing you, notice the small jumper
connectors. The jumpers are used to indicate which function you want to
activate.
To change the settings rearrange the small jumpers to the desired settings.
To Upload to the ESC do the following:
1. Ensure the transmitter and vehicle are turned off.
2. Make sure a battery pack is installed that has some charge in it.
3. Connect the battery to the vehicle.
4. Turn the power on to the ESC, wait for the Blue (or Blue/Yellow) LED to
come on.
5. Disconnect the Signal wire for the ESC from the receiver.
6. Connect the Signal wire to the top of the AQPC, ensure it is connected
correctly.

LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 13
7. Pay close attention to the ESC LEDs and you will notice the Red LED flash,
and on the AQPC the Red LED will come on. If you do not notice the ESC Red
LED flash, you can unplug the Signal wire from the AQPC and reconnect again
to verify the operation of the Red LEDs. Once you see the ESC Red flash and
the AQPC turn on Red, the ESC has accepted the programming.
8. Disconnect the Signal wire from the AQPC, turn off the power switch.
9. Reconnect the signal wire into the receiver.
10. The ESC has been updated and you are ready.
Note: If you should happen to lose any of your jumpers they are the
same jumpers used with computers and easily obtained at a computer
store.
ESC Warning LEDs
• If the Battery low voltage cutoff (LVC) is reached the Red LED will blink.
• The Red LED will automatically stop blinking should the battery voltage
recover above the chosen Low Voltage Cutoff.
• If the ESC has detected a thermal overload, the Yellow LED will blink. Let the
ESC cool down.
Setup / Calibration to Transmitter
To perform the setup/calibration between the ESC and Transmitter follow these
steps:

LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 14
1. Turn on the transmitter.
2. While turning on the vehicle Press and Hold the setup button, notice the
Yellow LED is now ON solid. When the Yellow LED is on solid, you can release
the setup button.
Note: If you cannot get the ESC to Calibrate, you may need to reverse your
Throttle Servo on the transmitter.
3. Using the throttle trigger pull Full Throttle until the Green LED is ON solid.
4. Next push the throttle trigger to Full Brake until the Red LED is ON solid.
5. Now return the throttle trigger to the Neutral position and the Blue LED is
ON solid.
6. Turn off the vehicle/ESC power switch.
7. Turn the vehicle/ESC back ON; you are now ready to use the ESC.
Normal Operation

LOSB9515 Xcelorin Electronic Speed Control v1.1 Page 15
• After turning on the vehicle, the Blue LED will be on for normal operation.
• If reverse is active then you will notice the Yellow LED is also on.
Confirmation of Full Throttle and Brake
• While the ESC is on and operational, if you pull the throttle trigger to Full
Throttle the Green LED will turn ON solid.
• Push the throttle trigger to Full Brake, the red LED will turn ON solid.
Note: If the transmitters brake endpoint adjustment is reduced after
calibration then the Red LED will not turn on.
ESC – reverse operation
Should you get into a situation that requires reverse, after you have applied
any brakes you may have needed, return the throttle trigger to the neutral
position. Wait a moment or two and then push the trigger forward for reverse.
Note: There is automatic protection within the Xcelorin ESC. Only after
you have stopped and returned the trigger to neutral will reverse
become available. If while traveling in reverse, pull the trigger to go
forward. This is to help prevent serious damage to the drive train.

Connect the Xcelorin ESC and Sensorless Motor
There are three wires from the ESC a Black, Blue and White for the motor.
Below see an Xcelorin Sensorless Brushless motor with the Protection Cap
removed for easy access and wire installation
Each wire will be soldered to a single motor tab. Make certain there is not a
short across any of the motor connections. If shorted together, you will
damage the ESC when the batteries are connected.
If the motor you are using runs backwards after installation, you can correct
this in one of two ways:
•Unsolder any two motor wires, switching the position on the motor and
re-solder.
•Using the ESC Software, you can select the Reverse Rotation feature.

Connecting the Xcelorin ESC to your Receiver
The Receiver wire will connect to nearly all current receivers. Plug it into the
Throttle Channel of the receiver.
