To power down the battery, press
and hold the power button until
the bottom LED (red) begins flash-
ing. The battery will go through a
countdown phase and then power
off, turning off the illumination on
the power button. A buzzer may
accompany the countdown phase
if enabled within the software.
BDI LED functions:
1. LEDs illuminated except bottom (red) – Normal operation showing bat-
tery SOC. The red LED is not illuminated until the battery SOC is below
20%
2. Solid red LED - Low SOC, battery should be charged soon
3. Red LED flashing - Battery shutdown, power button pressed or battery
fault
4. Combination of solid LEDs and one flashing LED - Battery charging.
The battery is connected to a charger and the flashing LED indicates
charging level
5. Buzzer sounding – Battery shutdown. User commanded shutdown (if
buzzer is enabled in software) or battery fault shutdown (buzzer cannot
be disabled for a fault related shutdown)
8.1.3 Battery Discharge Indicator (BDI) 2.0
The BDI 2.0 is a small
accessory used to
power the battery on/
off and display the
State of Charge (SOC).
BDI 2.0 requires a
specific harness
and would not be
compatible with a BDI 1.0 setup without replacing the BDI harness.
To turn the battery on, press and hold the BDI power button until all
LEDs are illuminated. The battery will power on and the appropriate
LEDs will remain illuminated, displaying the battery's SOC. The label
next to the LEDs references the battery SOC.
To power down the battery, press and hold the power button until
the LEDs begin to flash, then release the button. The battery will go
through a countdown phase and then power off, turning off the illumi-
nation on the power button. A buzzer may accompany the countdown
phase if enabled within the software.

8.1.4 CAN Integrated Trucks
If the forklift is equipped from the factory as Deka Ready Power lith-
ium-ready, connect the Navitas supplied communication harness be-
tween the lift equipment's lithium harness and the battery's CAN 1 port
(black 12-pin Deutsch connector). The battery will power on when the
12-pin connector is connected to the battery.
The forklift must be set to lithium mode to communicate with the
battery, otherwise the battery will shut down when the equipment is
driven. A "lithium ready" forklift has the wire harnesses and software
to work with a lithium battery, you may have to change the setting on
the truck to use the hardware and software. Consult the forklift dealer
for further details.
To turn the battery off, disconnect the black 12 pin connector on the
CAN communication harness, from the battery. The battery will go into
a countdown and then power off. Some CAN integrated trucks may
have a BDI 2.0 connected. In these situations, use the BDI's power but-
ton to turn the battery on/off.
8.2 Power Save Shutdown
The Power Save Shutdown is a feature in the battery's software to
prevent the battery from being over-discharged. Without this feature,
over-discharging could lead to permanent damage of the cells and re-
sult in loss of capacity or failure of the battery to function.
Power Save Shutdown is initiated when the battery reaches 0%, as
read on the UIM/BDI or truck display (if truck is CAN integrated). At this
point, the battery will enter a countdown phase before shutting off. The
Diagnostic Trouble Code (DTC), SOC_OORLO (State of Charge, Out of
Range Low) message will accompany this shutdown and can be read
on the Diagnostics screen of the User Interface Module (UIM).
The battery may be powered on immediately after this shutdown, but
it will only remain on for 2 minutes, allowing the forklift to be driven to
an approved charger. After 2 minutes, the battery will power down, as
outlined above. This process may be repeated 2 more times before the
battery will no longer power on and will have to be towed to a charger.
Only connecting to an approved charger will allow the battery to power
back on and begin charging.
8.3 Charging
Deka Ready Power Lithium batteries are not intended to be removed
from the vehicle for charging unless they are destined for storage. The
batteries communicate with the charger during charging to provide a
fast and safe charging event. Deka Ready Power batteries must always
be charged with approved chargers during regular operations. Chargers
may communicate with the battery via CAN or BMID communication.
It is recommended that the battery be placed on charge whenever
it is not expected to be used for more than 5 minutes. This will help
maintain the usability of the battery throughout the day. It is intended
that the Deka Ready Power will be charged during all breaks, lunches,
down-times, and ends of shifts. These frequent charges are not detri-
mental to battery performance or life.
8.3.1 Charging Types
All current model batteries are configured to work with CAN communi-
cating chargers. CAN charging optimizes communication between the
battery and charger while connected. Chargers will show an accurate
State of Charge (SOC) of the battery and balancing will be quicker and
more accurate.
Earlier models of Ready Power batteries were equipped for Battery
Module Identification (BMID) charging. Although older, this form of
