1.2 GENERAL WARNING
• WARNING! The voltage of this battery is strong enough to cause electric shock.
• Use the battery only as intended. The system must only be used to store electrical
power.
• Work on a lithium battery should be carried out by qualified personnel only.
• Use insulated tools. Do not wear any metallic items such as watches, bracelets, etc.
• Terminals of the lithium battery are always alive. Therefore, do not place items or
tools on the lithium battery.
• Do not allow the battery connectors to touch conductive objects such as wires.
• Avoid short circuits, too deep discharges and too high charge currents.
• Any uncovered battery material such as electrolyte or powder on the skin or in the
eyes must be flushed with plenty of clean water immediately. Then seek medical
assistance. Stains on clothing should be rinsed out with water.
• If the battery casing is damaged, do not touch the exposed electrolyte or powder
because it is corrosive.
• The battery is intended for indoor use only. Do not expose the cables outdoor.
• Do not open, dismantle, or repair the battery. Electrolyte is very corrosive. In normal
working conditions, contact with the electrolyte is impossible.
CAUTION！
The product must be installed by a qualified electrician only and must be accompanied
by a document confirming this. Do- it-yourself installation will void the warranty and
may damage the battery resulting in electric shock, fire, or loss of life.

• Lithium batteries are heavy. If involved in an accident, they can become a projectile!
Ensure adequate mounting, secure it, always use suitable handling equipment for
transportation.
• Handle with care. A lithium battery is sensitive to mechanical shock.
• Do not touch the battery with wet hands.
• Keep out of the reach of children and pets.
• Do not expose the battery to flammable or harsh chemicals or vapors.
• Do not paint any part of the battery, including any internal or external components.
The battery may explode. Do not drop, deform, impact, cut, crush or puncture it.
• Do not drag or step on the battery. Do not subject it to any strong force.
• Do not expose the battery to heat, fire, direct sunlight, liquids and moisture.
• Do not use a damaged battery.
• Contact the supplier within 24 hours if you observe abnormal operation.
• It is prohibited to insert any foreign object into any part of the battery.
• Servicing must be performed by qualified personnel only. All the battery terminals
must be disconnected for maintenance.
• Do not use cleaning solvents to clean the battery.
• In case of fire, you must use a type D, foam or CO2 fire extinguisher.
• The warranty claims are excluded for direct or indirect damage due to items above.
The manufacturer does not undertake any consequences or related responsibility which
results from violation of safety operation or violating of design, production and
equipment safety standards.

1.3 CHARGE AND DISCHARGE WARNINGS
• If the battery is stored for a long time, it is required to charge it every 6 months, and
the SOC should be at least 90%.
• After full discharge, the battery needs to be recharged within 12 hours.
• Do not connect the battery to PV solar wiring directly.
• Use only with an approved BMS.
• If the lithium battery is charged after being discharged below the "Discharge Cut-off
Voltage", or when the lithium battery is damaged or overcharged, it can release a harmful
mixture of gases such as phosphate.
• The temperature range within which the battery can be charged is 0 °C to 55 °C.
Charging the battery at temperatures outside this range may cause severe damage to
the battery and/or reduce battery life expectancy.
• The temperature range within which the battery can be discharged is -20 °C to 55 °C .
Discharging the battery at temperatures outside this range may cause severe damage
to the battery and/or reduce battery life expectancy.
1.4 TRANSPORTATION WARNINGS
• The battery must be transported in its original or equivalent package and in an
upright position. If the battery is in its package, use soft slings to avoid damage.
• Do not stand below the battery when it is hoisted.
• Never lift the battery at the terminals or the BMS communication cables. Only lift the
battery at the handles.

packaging complies with these instructions.
1.5 DISPOSAL OF LITHIUM BATTERIES
Batteries marked with the recycling symbol must be processed via a recognized
recycling agency. By agreement, they may be returned to the manufacturer.
Batteries must not be mixed with domestic or industrial waste.
Do not throw the battery into fire.
1.6 BEFORE CONNECTION
• After unpacking, check the product and the package content first. If the product is
damaged or its parts are missing, contact your local supplier.
