Operation manual

Keep this manual in a safe place for quick reference at all times.

This manual contains important safety and operation instructions for correct use of the battery charger.

Read through the manual and pay special attention to the markings and labels of the charger,

battery and equipment connected to the battery system.

Pay special attention to these two types of notices used in this manual.

Failure to heed this warning may cause injury to persons and damage to Equipment.

Failure to observe this warning may result in damage to equipment

and improper functioning of the Charger.

WARNING:

● The charger is not designed for any life saving application.

● The charger is designed for in-door use. Protect the charger from ingress of water.

● This charger is made to charge only properly sized lead acid based batteries and Lithium Fe PO4 (LFP).

● Don't recharging non-rechargeable batteries.

● Charging other types of battery or under-sized lead acid batteries may cause fire or explosion.

● Install the charger in accordance with all local codes.

● Do not use the charger if it has been dropped or damaged.

● Never attempt to charge a frozen LEAD BASED battery.

Never attempt to charge LFP battery below minus five degrees C.
Never attempt to charge LFP (Lithium FePO4 ) without built in.
BMS (battery management System).

● Never attempt to charge a damaged battery.

● Wear protective goggles and turn your face away when connecting or disconnecting the battery.

● Never place the charger on top of a battery.

● Never smoke, use an open flame, or create sparks near battery or charger during normal charging

operation as batteries may give out explosive gas.

● Do not charge batteries in an enclosure (box- in) due to possible explosion of entrapped explosive gas.

● If the charger does not work properly or if it has been damaged, unplug all DC connections of input and

output.

Introduction

Especially designed for vehicles with Smart Alternator, Start-Stop, Regenerative Braking system

The SBC-5925 is designed to address to the issues of wide swing of output voltages from the smart
alternator, braking regenerative EURO 5/6 vehicles in fully charging the house battery. It is suitable for use
with all old alternator system and distant house battery.
The charger Booster provides fast safe charging profiles for 4 types of lead based and 2 types of Lithium
FePO4 batteries.

The built-in vibration sensor makes it possible to use the charger by just connecting to the starter battery
terminal without touching the car’s electrical /electronic wiring thus avoiding any possible excuse of revoking
the car’s warranty.

The digital control design of SBC-5925 makes it automatically select & adapt to 12V or 24V input alternator/
battery system.

Multistage Charging

This is a select (battery type) and forget charger designed for fast and accurate recharge of your deep cycle
house battery. The smart multistage charging enables the charger to be connected permanently to your
battery banks without the worry of over charging or drying out the electrolyte.

Lead acid based Battery

A 3 Stage Bulk, Absorption & Float charging profile for 4 types of lead acid based battery with maximum
constant charging current at the Bulk Stage and a Constant Voltage with decreasing charging at the
Absorption Stage and a reduced voltage Float Charge for maintenance when battery is full.

LiFePO4 (LFP) Battery

A 2 Stage charging is specially for 2 types LiFePO4 battery and charging current stops at the end of
Absorption stage.

Three Charge Control Methods:

Ignition Control : Charger starts charging only when ignition is on and stops charging when

Vibration Sensor Control : Charger starts charging when repeated vibrations are detected and stops

Input Voltage Control : This is for non-intelligent alternator with sufficient high & uniform voltage.

Features

● Auto select for 12V or 24V car system.

● Design for all alternators, conventional, smart alternators, start-stop & regenerative braking.

● 3 DC Charge Control Modes to select: Vibration Sensor Control Mode.

Ignition Control Mode with Automatic on when ignition is on &
off when Ignition is off or Manual Control setting.
Input Voltage Control.

● Suitable for standard Lead Acid, AGM and Lithium Fe PO4 battery.

● 3 Stage charge for 4 types of Lead Acid based batteries.

● Specific 2 Stage charge for 2 types LiFePO4 battery.

Protections

● Self Recoverable Input Under Voltage Protection.

● Self Recoverable Output Over Voltage Protection.

● Self Recoverable Over Temperature Protection.

● Self Recoverable Over Load Protection (C.C.) with constant current at decreased output voltage.

● Self Recoverable Input Reverse Polarity Protection

● Output Reverse Polarity Protection by thermal fuse.

Ignition is off.

charging when no vibration is detected for over 2 minutes.

Charging is cut off easily due to high threshold voltage to protect starting
battery.
