1. General Safety Instructions
Carefully read all safety warnings, instructions, illustrations and specifications provided with this battery pack.
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term
"battery pack" in the warnings refers to your mains operated device which is a major part of an energy
storage system.
Please save all warnings and instructions for future reference.
Lithium batteries are classified as Class 9 hazardous material UN3480, a power source with high energy density and dangerous
materials in a closed metal case! All the recommendations contained in this document must be strictly applied in order to ensure
a safe and optimal use of the battery.
1) Misuse of the battery may lead it to overheat or ignite and cause serious injury. Make sure to follow the safety rules listed
below:
a) Never short circuit the battery terminals
b) Do not open the battery
c) Do not reverse the polarity
d) Do not overcharge or over-discharge
e) Always comply with the voltage range given on the battery label
f) Do not disassemble the battery
g) Do not use the battery without its electronic management system
h) Do not subject the battery to excessive mechanical stresses
i) Do not expose the battery to water or condensation
2) Do not place the battery on or near fires, or other high temperature locations (> 70°C). Doing so may cause the battery to
overheat or ignite. Using the battery in this manner may also result in a loss of performance and a shortened life
expectancy.
3) Immediately disconnect the battery if, during operation, battery emits an unusual smell, feels hot, changes shape, or
appears abnormal in any other way.
Dangers involved in case of fire:
1) Danger of dust particle explosions:
a) Decomposition through fire or heat under development of toxic and cauterizing gases
b) Combustion gasses which strongly irritate eyes and respiratory organs
c) General actions to be taken by the driver if these dangers occur:
2) Recommended handling process:
a) Put a warning signal on the road to warn others
b) Inform others about the danger and direct them to stand away from the wind direction
c) Call police and fire fighters immediately and notify them that lithium batteries (UN3480) is onboard
3) Instruction for fire extinguishing:
a) Extinguish with water, if possible cover battery completely in water
b) Extinguishing with water will produce fluoride, phosphate, fluoride-oxide and carbon-oxide.
c) Alternatively extinguish with a CO2 extinguisher.
Important note: when put to storage the battery must be fully charged and must be charged again every 6 months.

3. Installation Guide
1. Unpack the product, and please do visual-inspect the appearance of the product, make
sure the product is intact, no damages during the transport.
2. Compare the packing list below and check the completeness of attached parts and
components.
3. Please contact your local supplier if any damages and missing parts are noticed.
1. Inspect the ambient temperature to make sure it stays between -20℃to +50℃(preferably
0℃to -40℃). If the device is exposed to extreme cold environment (below 0℃) for long
hours, its life cycle will be reduced.
2. Place the device in areas with good ventilation and be away from danger factors such as
water, combustible gas, and corrosives.
3. Avoid long-hour installation in corrosive environment.
4. Avoid direct sun explosion.
5. If installed in low temperature environment, it might be subject to water condensation.
Don’t continue until the inside of the machine is completely dry, or you may get electric
shock.
6. In case of any emergency, please immediately stop battery pack charge /discharge and
shut down the machine.
7. All power plugs should be connected to the protection ground line.

If the system doesn’t work properly on starting, please do not rush to conclude there is a
fault. You might as well refer to the table below to trace the possible causes. You could
also check the external environment factors which can be improper temperature and
humidity conditions or overload. If you have done everything specified in this table and still
unable to make it work normally, please contact Sunwoda local office or supplier for help
You can also contact with us to resolve the trouble, please provide following information to
facilitate the handling process:

6. Maintenance rec ommendation
■Operation environment
–In order to increase products’ life cycle, a good installing environment should be sustained.
Usually, it is suggested to avoid long-hour exposure to strong light and other forms of
radiation, keep away from water, other liquids, and ash /mud.
–Exposure to the heat of sun is strictly forbidden. Overheat environment can reduce battery life
cycle.
■Fault alarm handling
–In the process of operation, if there is a fault alarm, please refer to fault description in Part 5 in
time for correspondent handling method to avoid damages to the system.
■Charge and discharge
–Avoid large current discharge;
–Charge the device in time if the power is low so as to avoid momentary large current discharge
–Track the charge hour effectively:
–Charging with 40% remaining capacity is optimal.
–Monthly charge and discharge is proposed in order to increase battery life.
■Routine maintenance
–Undercharge is forbid in time of battery storing, (undercharge means the battery is not
charged in time after using).If not in use, battery should be recharged monthly to maintain a
good state and increase life cycle.
–If the standby time drops significantly in a short span when in use, it’s probably due to voltage
imbalance between cells. Please immediately turn to the supplier or after-sale service point for
checking, repairing and matching in order to increase cycle life.
–Check all the connectors and plugs. If any loosening occurs, please adjust immediately.
–Check if the wires and cables wear any abrasives. If any, adjust timely.
15- Instruction Manual for NEO pro B4180 Module -
•Please make sure the load is disconnected to power and the
system is shut down before inspection and maintenance
•Avoid leaving metal or other parts in the system in case of short
circuit and damage
Important!

7. Warranty and after sales service
■The standard warranty is five(5) year from the date of purchase.
–Issue free repair when a valid certificates from the distributor is presented.
–Provide free repair service when a serial number is offered.
