CABRA OWNER’S MANUAL

constantly communicating with each other to keep their speed synchronized to improve
traction in muddy or loose terrain. The Cabra drives a little differently than typical internal
combustion engine vehicles. The position of the foot throttle determines the speed the
motor controllers are targeting to achieve. When the driver takes their foot off the
throttle the controllers will begin slowing the vehicle using regenerative braking. Under
normal conditions the foot brake is hardly used unless trying to stop fast or going down a
steep hill.
In some cases, regenerative braking can be diminished so the driver
should always be ready to use the foot brake if needed.

lithium ion battery pack and charging
-
The most expensive component in the
Cabra is the battery pack. There is a battery management system (BMS) installed which
constantly monitors multiple parameters of the battery pack and controls other
components in the Cabra to protect the battery pack. Multiple diagnostic pages are
available to the user on the display. If the Cabra does not seem to drive normally, contact
UTD and we can usually diagnose over the phone while the user is looking at the
diagnostic pages.
The cabra should never intentionally be driven below 5% state of charge (soc).
At 5% the BMS will significantly reduce power output and shut down if it gets too low.
Leaving the battery pack at a low SOC will damage the pack.
The Cabra can be charged at 120V or 240V. At 120V it will take approximately 13 hours to
charge to 95% from 5% SOC. At 240V it will take a little over 3 hours to charge to 95%
from 5% SOC.
The full state of charge on the Cabra is de-rated to 97% to increase the longevity of the
battery pack.
When storing the Cabra for long periods of time it is best to leave it with a 40-70% SOC
and not leave it plugged in. The Lithium Ion batteries maintain their charge state
extremely well and should not lose more than 3% SOC per month.
Leaving the battery
pack at full charge can diminish the longevity of the pack and letting the pack
fall to 0% SOC will ruin the battery pack.
Charging is achieved by using one of the supplied adapters to plug into a 120V or 240V
outlet.
Do not use any other adapters than those supplied with the vehicle as
doing so can cause damage to the vehicle.
If you need a different adaptor, contact
UTD, and we can probably make you one.
