XL-5 HV Battery Settings (Low-Voltage Detection Setting)
The XL-5 HV electronic speed control is equipped with built-in Low-
Voltage Detection. The Low-Voltage Detection circuitry constantly
monitors the battery voltage. When the battery voltage begins to
reach the minimum recommended discharge voltage threshold
for LiPo battery packs, the XL-5 HV will limit the power output to
50% throttle. When the battery voltage attempts to fall below the
minimum threshold, the XL-5 HV will shut down all motor output.
The LED on the speed control will slowly blink red, indicating a low-
voltage shutdown. The XL-5 HV will stay in this mode until a fully
charged battery is connected.
When you turn your model on, the XL-5 HV speed control’s status
LED will glow green, indicating that Low-Voltage Detection is
activated to prevent over-discharging of LiPo batteries. LiPo
batteries are intended only for the most advanced users that are
educated on the risks associated with LiPo battery use.
Verify that Low-Voltage Detection is ACTIVATED:
1. Turn on the transmitter (with the throttle at neutral).
2. Connect a fully charged battery pack to the XL-5 HV.
3. Press and release the EZ-Set button to turn the XL-5 HV on. If the
LED is solid green, then the Low-Voltage Detection is ACTIVATED.
If Low-Voltage Detection is DISABLED:
1. Make sure the LED on the XL-5 HV is on and RED.
2. Press and hold the EZ-Set button (the
LED will turn off). After ten seconds, the
motor will beep twice and the LED will
shine GREEN. Release the button.
3. Low-Voltage Detection is now ACTIVATED.
For NiMH battery users, follow these steps to disable Low-Voltage
Detection (NiMH setting):
1. Make sure the LED on the XL-5 HV is on and GREEN.
2. Press and hold the EZ-Set button (the
LED will turn off). After ten seconds, the
motor will beep three times and the
LED will shine RED. Release the button.
3. Low-Voltage Detection is now DISABLED.
XL-5 HV Setup Programming (Calibrating your ESC and transmitter)
Read through all of the programming steps before you begin. If you
get lost during programming or receive unexpected results, simply
unplug the battery, wait a few seconds, plug the battery pack in, and
start over.
1.
Disconnect one of the motor wires between the
XL-5 HV and the motor. This is a precaution to
prevent runaway when the speed control is turned
on before it is programmed.
2. Connect a fully charged battery pack
to the XL-5 HV.
3. Turn on the transmitter (with the
throttle at neutral).
4. Press and hold the EZ-Set button (A).
The LED will first turn green and then
red. Release the button.
5. When the LED blinks RED ONCE, pull
the throttle trigger to the full throttle
position and hold it there (B).
6. When the LED blinks RED TWICE, push the
throttle trigger to the full reverse and hold it
there (C).
Note: If you are calibrating to clear an error code on the ESC, then
skip step 7 and proceed to step 8.
7. When the LED blinks GREEN ONCE, programming is complete.
The LED will then shine green or red (depending on Low-
Voltage Detection setting).
8. When the LED blinks GREEN ONCE, continue holding the trigger
in the reverse position and also press and hold the button on
the ESC for about 10 seconds until the ESC beeps. This places
the ESC in NiMH mode and clears any error codes.
XL-5 HV Operation
To operate the speed control and test the programming, reconnect
the motor wires and place the vehicle on a stable block or stand so
that all of the driven wheels are off the ground.
Note that in steps 1-8 below, Low-Voltage Detection is ACTIVATED
(factory default) and the LED shines green. If Low-Voltage Detection is
DISABLED, the LED will shine red instead of green in steps 1-8 below.
1. With the transmitter on, press and release the EZ-Set button. The
LED will shine GREEN. This turns the XL-5 HV on. If you press and
A
Green then Red
B
Once Red
C
Twice Red
D
Solid
WARNING: FIRE HAZARD!
Do not use LiPo batteries in this vehicle with
Low-Voltage Detection disabled.
