TIPS
SAFETY
»DO NOT Short circuit
»DO NOT Reverse connections from charger to battery
»DO NOT Disassemble
»DO NOT Throw into re or incinerate
»DO NOT Heat above 60°C
»Discontinue charging your battery if you see smoke or swelling.
»Never leave your battery unattended at any time when being
charged or discharged.
»Do not expose the battery to moisture or water.
»
It is highly advisable to invest in a dedicated Low Voltage Disconnect
(LVD) to safeguard your battery from being discharged to a low
voltage, which can negatively affect its lifespan. In the event that
an LVD is not available, the battery must always be adequately
charged to prevent over-discharge.
»
The voltage of a LiFePO4 battery measured during the charging
process is not a reliable indicator of its actual voltage. To obtain
an accurate measurement, it is recommended to let the battery rest
for 15 minutes before testing its voltage.
CAUTION: RISK OF FIRE,
EXPLOSION OR BURNS.

CHARGING
RECOMMENDATIONS
1. Ensure the battery cables are tight, secure and have a good
connection.
2. Follow the instructions on the battery charger.
You can also charge the battery using a solar panel and a
compatible regulator with a lithium profile (select LiFePO4 mode
on solar regulator).
We recommend setting the solar regulator to the following
parameters:
»Overcharge Protection Voltage: 15V
»Overcharge Recovery Voltage: 14V
»Over-discharge Protection Voltage: 10.8V
»Over-discharge Recovery Voltage: 11.2V
The battery should not be charged directly through a
vehicle’s alternator.
NOTE: Use a 14.6V lithium AC to DC or DC to DC
battery charger to maximise the battery`s usable
capacity.
DO NOT USE A LEAD ACID VEHICLE BATTERY
CHARGER.
You won’t be able to fully utilize the battery’s usable
capacity if you use an inappropriate charger or
charge it at a lower voltage.
When charging, don’t set the charger
to a voltage greater than the battery’s
nominal voltage, as it may permanently
damage the battery.

BATTERY RE-ACTIVATION
HOW TO RE-ACTIVATE A BATTERY THAT NO LONGER CHARGES
The over-discharge protection voltage for this battery is set at 10V,
and if the voltage drops below this level, the Battery Management
System (BMS) will trigger a safety cutoff to protect the battery.
In such an event, you must follow the reset procedure for the battery
as outlined below:
METHOD 1 (EASY)
1. Disconnect the load from the battery and set it aside for at least 30
minutes.
2. The battery should recover to anormal voltage level
automatically.
3. The battery can then be fully charged for normal use.
It is important to note that in some cases, METHOD 1 may not be
sufficient, and you may need to proceed with METHOD 2 or METHOD
3 to reset the battery.
METHOD 2 (REQUIRES A CHARGER WITH 0V FUNCTION )
1. Use a charger equipped with a 0V charging function.
2. Charge the battery fully using this charger on its 0V setting.
3. Once the battery is fully charged, the BMS will reset automatically.
4. The battery can now be used as normal.
METHOD 3 (REQUIRES A SECOND BATTERY)
A lead-acid battery with a voltage more than or equal to 12V and
less than or equal to 14.6V will also work.
1. Connect the battery in parallel with another fully charged 12V
lithium battery.
2. Allow the battery to charge in parallel for at least one minute.
3. Disconnect the second battery and charge your battery fully
using a regular lithium battery charger.
4. Once fully charged, the BMS will reset automatically, and the
battery can be used normally.

LONG-TERM STORAGE
1. Connect the battery to an appliance and allow it to discharge
without reaching the over-discharge voltage level.
•LiFePO4 batteries have a low self-discharge rate of 2% per month.
•To prevent excessive discharge during storage, store LiFePO4
batteries at an 80% state of charge (SOC) if storing for longer
than six months.
•Failure to charge the battery before storage can cause over-discharge,
resulting in the battery's discharge level falling below the protection
level of the BMS.
•It is strongly recommended to store the battery at room temperature,
particularly for extended storage periods.
2. Charge the battery until it reaches 100%.
3. Reconnect the battery to an appliance and discharge it to
reduce its charge level back to 80% before storing.
Cycling through the battery power every 6 months is an
excellent way to add to the longevity of your battery.
To cycle through the battery's power:
To prolong the battery's lifespan, it is advisable to
store it at an 80% charge level.
Store the battery in a reproof container
Keep out of reach of children
