Installation & First time use
1. Install the Constant Current Power Supply (CCPS) dedicated
to charge the Smart Module. Check that the voltage printed on
the label corresponds to the nominal voltage of the battery, and
that the mains voltage corresponds to your AC network voltage.
2. Install the Smart Module by arranging the CCPS cord so that
it is accessible to connect it to the module, but not too close so
that heat generated from the CCPS will not be transferred to the
battery. Connect the CCPS to the Smart Module. Connect the
CCPS to the mains. The Smart Module status LED will be
orange.
3. Charge the battery until a green fixed status LED is
displayed. It may take longer than 48h for the first complete
charge.
4. Unplug the CCPS from the mains and unplug the Smart
Module. Check the LEDs shown by the Smart Module. When
pushing the button the 5 Gas Gauge LEDs should light up in
red.
5.Connect the main poles of the Smart Module to your
application (draining less than the 40A maximum current
available for the Smart Module) The battery should provide the
required current to the application.

Charging the battery:
When charging the battery, the charge status is indicated by the
status LED:
Orange
Initialization phase / Fast charge:
First check that the voltage > 0.8V/cell and the
temperature within [-10°C;+40°C]
If temperature > 50°C , charge duration will be
longer
The fast charge duration varies with the state of
charge of the battery
Orange
Green
Balancing charge
Battery already operational; more than 95% of
capacity charged.
Current is reduced to perform the balancing of
all the cells within the battery, depending on their
measured status
Green
Trickle charge
Balancing has been completed, battery will
provide its full capacity
Battery should be left this way until next use to
maintain it fully charged
Flashing
red
Defect, no charge
Contact your reseller or have a look at our FAQ
list (page 12) to see which maintenance actions
could be realized

Using the battery:
Connect the battery discharge cables to the main discharge
poles (1 & 6 as indicated on the front cover photograph of this
manual). Switch on the appliance and use until the battery is
fully discharged. Depending on the current drained in the
battery, the status LED indicates the following:
Green
Discharge
If the discharge current is higher than 100 mA,
the gas gauge LEDs light up
When the signal on Specific
PreAlarm
connector is ON, the battery is close to the end of
discharge
Orange
Regenerative charge
Battery receives a charge current higher than
100 mA
When the signal on Specific
PreAlarm
connector is ON, the battery is close to
regenerative charge limit (*)
When the regenerative charge is not allowed,
the battery switches to Charge mode and may
pulse the incoming current
OFF
Standby, battery disconnected
No voltage on main discharge poles
(*): only when the regenerative alarm option is selected For
some configurations, the battery can accept a regenerative
charge. This function allows recovering energy from a motor or
a reversible device powered by the Smart Module.
It is recommended to start to use the battery when the battery
temperature is in the -10°C to +40°C range.
It is possible to start the discharge from -20°C to +60°C
occasionally. However the service life will be reduced by using
the battery at high temperatures.

If the Smart Module temperature reaches 65°C, the discharge is
stopped by the control system to protect the battery. In this
case the status LED will turn off and the gas gauge indicator will
still indicate the real battery state of charge when pushing the
button. The battery is not empty and will be able to discharge
again after cooling down below 55°C.
The battery goes in sleep mode after a long rest.
To wake up the battery:
• Press the push button
• OR connect a charger
• OR use the Key signal on the Specific connector
Specific connector:
The 8-pin Specific connector (charge and communication) is
connected this way:
To connect to the Specific connector, use the mating connector

Defect mode:
In case of defect, the electronics immediately disconnects the
battery (main poles and charge pins on Specific charge and
communication connector) and displays a defect signal on the
status LED for one minute.
If the defect disappears, the Smart Module can be restarted by
pushing the gas gauge button.

Storage recommendations:
It is recommended to always store the battery connected to the
charger that will maintain a trickle charge.
In case the battery cannot be connected to the charger during
storage, the battery should be stored disconnected from the
appliance and in a dry and cool location. Typically, a fully
charged battery can be stored 6 months in a temperature range
between 25°C and 35°C and a relative humidity of 65%.

Gas gauge:
To check the available capacity left in the battery, press the
push button.
The 5-level display corresponds to the following state of charge:

During use, to keep the accuracy of the gas gauge, it is
necessary to regularly fully discharge the battery according to
the following procedure (calibration cycle):
First, fully charge the batteries until status LED becomes
green.
Then, fully discharge until it is stopped by the battery.
If the decrease in capacity is more than 5%, it will be necessary
to do several calibration cycles.

State of health:
The Smart Module includes a state of health (SOH) indicator
that calculates the battery ageing and allows anticipating the
end of life.
To check the state of health of the battery, depress the push
button for >2 seconds.
The 5-level display corresponds to the following state of health:

CAUTION:
NEVER
• Immerse the battery or pour water on the battery.
• Use improper CCPS to charge the battery.
• Reverse charging of the battery.
•Open battery outside of authorized network, disassemble the
battery blocks or cells (be aware that alkaline electrolyte is
contained inside, and electrolyte exposure can be harmful).
• Short-circuit the battery (e.g. introducing a metallic part in the
connector).
• Discharge the battery outside the predefined range conditions.
•Expose the battery to high temperatures (may activate the
safety protections at the cell and battery level).
• Expose the battery to fire.
Warning
• If any leakage of electrolyte occurs, stop using the battery
immediately. Electrolyte is corrosive to some metals.
• If electrolyte comes in contact with your skin or clothes,
immediately wash with soap and water.
• If electrolyte comes in contact with your eyes, wash thoroughly
with water and immediately consult a doctor.
Electrical Hazards
With the typical connection on a 36V battery, the main battery
poles and the charge poles can operate normally over 50 volts
during charge. Bodily contact with 50-60 volts may cause a mild
shock.
Batteries are capable of delivering short circuit currents of more
than one hundred amperes.
• Do not wear rings, watches, bracelets, etc. when working on
batteries.
Short-circuit currents through these objects can cause serious
burns or injuries.
