WHAT IS LiFePO4?
Lithium Iron phosphate (LiFePO4) batteries are a type of
lithium ion (Li-Ion) rechargeable battery in which lithium ions
move from the negative electrode (anode) to the positive
electrode (cathode) during discharge and back again when
being charged. LiFePO4 batteries provide reliable power, are
environmental friendly containing no toxic substances, fast
charging and long lasting in a compact, lightweight package.
BATTERY CARE
To ensure a long and safe life from your battery, please ensure
you consider the following:
• Store where it’s dry, clean, shaded and well-ventilated at a
temperature between 0°C to 40°C when charging.
• During storage store at approx 50% State of Charge (SOC).
• Charge every 6 months if in an unused situation.
• Keep the top of the battery and its terminals clean.
• Protect the battery from being dropped, turning over and
serious stacking during loading.
• Can be mounted on it’s side.
The lifespan of a deep cycle battery will vary considerably with
how it is used, how it is maintained and charged, temperature,
and other factors. With good care, your Lithium battery should
have a long lifespan.

INSTALLATION
Your Lithium LiFePO4 Deep Cycle Battery is designed for
single, series or parallel use. Only connect batteries of the
same type, model, capacity, and age.
This battery is not designed for, nor should it be tted into an
engine bay or other area subject to high heat.
To install your battery:
• Before making any electrical connections to or from your
battery, secure the battery in place. Fasten tightly and make
provisions for shock absorption if exposure to shock or
vibration is likely.
• Once secured in place, unscrew the metal nut from the
terminals with a spanner or adjustable wrench, red (+)
positive, and black (-) negative. Be careful not to short-
circuit the battery with any metal objects across the
terminals.
• Ensure the charging source
cables have M8 ring terminals
suitable size to match the
battery M8 terminals.
• NOTE: Do not place anything
such as a washer between the
battery terminal and the cables.
• Connect the charging and load
cables to the battery, red (+)
positive, and black (-) negative. Fastening the nut for each
tightly without excessive torque or over-tightening.
• It is good practice to ensure that the connections are re-
torqued and the batteries are cleaned periodically.

CYCLES VS LIFE
The lifespan of a Lithium LiFePO4 Deep Cycle battery is
directly related to how deep the battery is cycled each time.
A cycle is what percentage of the battery capacity is being
used each time, when discharging from fully charged to a
percentage Depth of Discharge (DOD) and then charging to
full again. The DOD describes the percentage of the battery
capacity used each time.
Check your battery specications for the expected life cycle.

BATTERY MANAGEMENT
Your Lithium LiFePO4 Deep Cycle battery is equipped
with an internal Battery Management System (BMS). The
BMS monitors the battery’s state and ensures the safety of
operation.
INTERNAL BATTERY MANAGEMENT SYSTEM
For Lithium Deep Cycle batteries equipped with an internal
BMS, the BMS will control the charging ow and ensure your
lithium battery is safely charged under the correct charging
parameter. There are 2 temperature sensors (1 for prismatic
cells and 1 for the BMS itself) to protect against over-
charging, over-discharge and short-circuiting. The BMS will
limit discharge, manage cut-o voltage and protect the inner
cells. It also contains a circuit that handles cell balancing,
low voltage cuto, high voltage cuto, short circuit protection
and high temperature protection improving performance and
increasing the longevity of the battery.
BLUETOOTH MONITORING
Lithium Deep Cycle batteries equipped with a Bluetooth
enabled BMS can be monitored via Bluetooth with a
Smartphone and the SMART BMS App.
Use the app to access accurate data from your battery including
current cycles, current state of charge, minimum/maximum
voltages and view individual voltages of each battery cell.
To connect to your Smartphone
1. Download the SMART BMS App from the Apple App Store
or Google Play for Android
2. Connect to your battery with Bluetooth
3. Monitor your battery

CHARGING YOUR BATTERY
Your Lithium LiFePO4 battery arrives approx 30% charged
and will require a full charge before use.
CHARGE THE BATTERY
• When the voltage is lower than 12.8V, the battery should be
charged as soon as possible rather than discharging again.
• The charging voltage should be lower than 15V during
charging the battery.
Pending the BMS inside the battery, capacity of the battery
and size of the charger used, a Lithium battery can take
anywhere from 3 to 12 hours to fully charge.
Voltage Capacity
14.4V 100%
13.6V 100%
13.4V 99%
13.3V 90%
13.2V 70%
13.1V 40%
13.0V 30%
12.9V 20%
12.8V 17%
12.5V 14%
12.0V 9%
10.0V 0%
This chart shows the resting
voltage of a lithium battery
compared to its state of charge
in percentage, this is only a guide
and accuracy may vary depending
on what you are using to measure
the voltage. The voltage should
be measured while the battery
is resting, not while charging or
discharging as that will skew the
results. 13.4V or above resting can
be considered fully charged.
CHARGING WITH A BATTERY CHARGER
To ensure that your battery can charge fully and in a
reasonable amount of time, the charger:
• does not have to have a lithium prole to work.
• does need to be the right size for your battery and output
power in the correct voltage range.
• with a Lithium prole, should be at least 10 Amps.
• without a Lithium prole, should be at least 15 Amps, set to
AGM as this tends to be the closest in voltage to what the
lithium batteries want to charge at.
If you have a large battery over 200AH or multiple batteries
totaling more than 200AH then we recommend using a charger
at least 10% of the size of the battery, so a 300AH battery
bank would need at least a 30 Amp charger.
If your charger does not meet the requirements, it won’t
damage the lithium battery due to the inbuilt safety measures,
but it may not charge the battery or only charge to a low level.
If this is the case contact the retailer for a range of Ardent
Lithium Battery Chargers.

CHARGING WITH A SOLAR CHARGER SOURCE
Your Lithium Deep Cycle battery can be charged with solar
panels. Make sure to use a Maximum Power Point Tracking
(MPPT) Regulator to regulate the voltage and current output of
your solar panels to eciently charge your lithium battery.
Conversely, add an Ardent Battery Box with Anderson Plug
Connections. An Anderson style plug is a moulded, heavy-duty
connector designed for high current 12V circuits. They are
commonly used to create a safe and secure power connection
between a battery and the solar panels. Most modern caravans
and campers have an Anderson style plugs installed from
factory.
CHARGING TOO HIGH
If you charge your Lithium Deep Cycle battery above 15V for
a 12V battery, the BMS inside the battery terminal will turn
o. The cut-o voltage settings will vary slightly depending on
current levels, temperature and part tolerances.
To turn ON the battery again, disconnect the charging source
and let the battery rest for several seconds (~30 sec). It should
come on.
If the 12V battery has voltages higher than 18V, the internal
BMS is damaged and will not turn ON. Battery life for a lithium
battery can be enhanced by not discharging the battery to 1Ah
capacity or BMS lower voltage cut-o settings. Discharging
down to BMS lower voltage cut-o settings can quickly
decrease the life of the battery. Discharge down to 20%
capacity remaining then re-charging the battery.

If you have a charged battery
(E.G. car battery) and jumper
cables, follow the below steps in
sequence to bring your Lithium
battery out of safe mode.
1. Disconnect all loads/inputs from
the Lithium battery.
2. Connect the Lithium battery in
parallel to a dierent battery
