Manual Instruction
Read the instruction manual carefully and make sure that you have
understood the contents before you use the product. When installing, using
and maintaining the battery, the user safety must be guaranteed.
1. General information
A lithium battery is required to achieve a stable power supply even under
heavy loads, absolutely the best replacement for a lead battery. In addition to
the extremely light weight advantage, it offers additional enormous energy
reserves. Thanks to the integrated BMS (battery management system), BeLY
LiFePo4 batteries for 12V DC applications. An increase in capacity through
further LiFePo4 batteries can be easily implemented. The lithium iron
phosphate battery is the safest of the regular lithium battery types. The
nominal voltage of a LiFePO4 cell is 3.2V. A 12.8V LiFePO4 battery therefore
consists of four cells connected in series.
BMS
BATTERY MANAGEMENT SYSTEM
The battery installed in every battery Management system (BMS) ensures that
the battery in the event of under voltage or overload switches off and
automatically again turns on as soon as the problem is resolved.
EASY REPLACEMENT THE EXISTING BATTERY
The dimensions of the housing are identical with the most common AGM,
lead acid or GEL batteries. With optionally available round poles can also use
existing pole, terminals can be reused. An exchange the battery holder or a
change the loading structure is not necessary.
APPLICATION AREAS
The areas of application of this battery are specifically for the stationary or
mobile area. Lithium batteries are diverse. Especially Mobile homes, solar, e-
boats, electric scooters, golf carts or electro-mobiles / wheelchairs and
cleaning machines will always be more often equipped with it.
BATTERY CHARGING
Use the suitable lithium battery charger. Waiting until the battery is fully charged.
PERFORMANCE / EFFICIENCY
A SBL LiFePo4 battery can do more than 96% of the energy made available
directly to save. A 100% utilization of the existing capacity takes place with
the same output voltage.

1.2. BATTERY MANAGEMENT SYSTEM
The battery management system (BMS) built into each battery ensures that
the battery switch off in the event of under voltage or overload and
automatically again turns on as soon as the problem is resolved.
THE ADDITIONAL FUNCTIONS OF SBL BMS ARE:
- Protection of the cell against under voltage by switching off the load in good
time.
- Protection of the cell against over voltage by reducing the charging current
or switching off the charging process.
- Shutting down the system in the event of excess temperature.
-Charging of the battery is stopped in case of under temperature.

2. SAFETY GUIDELINES AND MEASURES
2.1. Intended Use
PLEASE FOLLOW THESE INSTRUCTIONS AND SAVE FOR FUTURE.
LOOK AT NEAR TO THE LITHIUM LIFEPO4 BATTERY.
The battery may only be used for the purposes described in the operating
instructions.
Use for other purposes is considered improper use and has the invalidity of
the result in product guarantee. The manufacturer is not liable for damage
caused by faulty, improper use or improper use of the product. Use in aviation
or in medical devices that serve to support life contradict the intended use.
LiFePO4 Batteries are designed for use as energy storage. Possible areas of
application for the battery are used as a service and on-board battery in
leisure vehicles or boat.
2.2. MARKINGS
Conformity mark (CE mark).
RoHS Conformity according to RoHS directive.
Conformity mark for material safety data sheet.
Fire, naked flames and smoking are prohibited! Sparking when handling
avoid cables and short circuits.
Not waterproof.
Dispose of the Lithium LiFePO4 battery in accordance with your local, state,
and local authority, federal laws and regulations. Batteries can be sent to the
manufacturer, can be returned. Do not mix with other (industrial) waste.
This product or parts of this product can be recycled.
The connections of the lithium battery are always live. Therefore, never place
objects or tools on the lithium battery. Avoid short circuits. Use isolated tools.
Do not wear metallic objects such as watches, bracelets, etc. on your body.
Use at a class D fire extinguisher, foam or CO2 fire extinguisher.
2.3. STORAGE AND TRANSPORT INFORMATION
The battery must be packed and protected well during transport.
The lithium battery must be transported according to the rules for transport,
these should always be followed (transportation code UN3480/UN38.3).
Never lift the battery by the terminals, only by the handles.
The battery should be stored in temperatures from -10℃ to +30℃.
During transport, the battery should be about 50-60% charged.
The battery should be charged every six months to keep it active so that it
always works maximum.
2.4. DISPOSAL
Batteries that are marked with the recycling symbol must be returned to
approved recycling points. You can also contact the manufacturer by
arrangement to be returned. Batteries must not be disposed of in household
or industrial waste.
2.5. IMPORTANT INSTRUCTIONS
Do not open the LiFePO4 battery without consulting the dealer. Unauthorized
opening of the battery voids the manufacturer's warranty.
▪ Only use the battery for the application for which it is intended.
▪ Do not short-circuit the LiFePO4 battery. The cable connections to the
consumers must go through a backup to be protected.
▪ Installation and maintenance may only be carried out by qualified
specialists.
▪ Do not expose to permanent direct sunlight. Protect from the effects of
heat. Temperatures above +60 ° C can damage the battery.
▪ Use only compatible chargers. The battery is in a longer storage of all
disconnect devices.
▪ Pay attention to proper assembly.
▪ Avoid damage of any kind, for example by falling, drilling, etc. (Risk of short
circuit).
▪ Always keep the battery dry and clean.
▪ Note the plus (+) and minus (-) markings on the LiFePO4 battery and the
device and pay attention to the correct polarity.
▪ The cycle capacity may vary due to the change in the working temperature
and the charge and discharge rate differ from the nominal capacity.
▪ Only suitable for parallel connection. Series connection is not permitted.
Before connecting, bring to the same charge level. Batteries from different
manufacturers or different types should not be interconnected.
3. INSTALL THE BATTERY
Make absolutely sure that the LiFePO4 battery is not connected with reversed
polarity. Should the battery be connected incorrectly, the BMS electronics will
be irreparably damaged and must be replaced with a new BMS board. This is
not a warranty case.
The battery is Not in serial connections suitable!
Disregard can lead to a defect!
