Manual Instruction
Read the instruction manual carefully and make sure that you understand 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), SBL 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.
It accepts parallel connections for increased capacity and serial connections for
increased voltage, max connections four batteries.
BMS
BATTERY MANAGEMENT SYSTEM
The battery Management system (BMS) installed in every battery 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 electron-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
ASBL 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 goodtime.
- 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 will be 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.
