SBL LFP-24V50AHBLH User manual

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 acid 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 are for 12V DC
or 24V 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 and a 25.6V
LiFePO4 battery consists of eight cells connected in series.
The battery is integrated Bluetooth. Bluetooth app can be loaded down by the look
on “ SBL Connect”(App Store or Google play).
It accepts parallel connections for increased capacity and serial connections for increased
voltage. Max serial connections four batteries for 12V series and max serial connections
two batteries for 24V series (max. 48V).
The battery consists of two energy-efficient heating elements controlled fully automatically
by the BMS, which use the charging current to bring the cell temperature constantly above
freezing point, thus guaranteeing maximum charging and discharging performance even at
extreme temperatures.
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
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 the battery is stopped in case of under temperature.
