How to Use

Follow the instructions in the SG48100M user manual. Battery installation, electrical connections, and system configuration should be handled by a qualified professional.

Step 1: Review the Safety Instructions

Read the user manual and all battery precautions before use. Keep the battery away from direct sunlight, rain, excessive temperatures, and hazardous materials.

Step 2: Check Battery Connections

Ensure the battery is connected with the correct polarity. Reverse-polarity charging and short circuits are prohibited.

Step 3: Activate the Battery

When the Battery Management System is in its dormant state, press and hold the control button for 3–6 seconds, then release it.

The protection board will activate, and the LED indicators will illuminate sequentially.

Step 4: Monitor Battery Status

Use the LCD display and battery indicators to monitor operating information.

The battery's LED indicators communicate operating conditions, charging and discharging activity, battery capacity, and alarms.

Step 5: Place the Battery into Sleep Mode

When the Battery Management System is active, press and hold the control button for 3–6 seconds, then release it.

The protection board will enter sleep mode.

Step 6: Reset the Battery Management System When Necessary

When the BMS is active, press and hold the control button for 6–10 seconds, then release it.

All LED lights will illuminate simultaneously for 1.5 seconds to indicate the reset.

A reset retains the parameters and functions previously configured through the host computer.

Important Safety Precautions:

• Do not short-circuit the battery.

• Do not disassemble, puncture, crush, or burn the battery.

• Do not expose the battery to rain or direct sunlight.

• Do not expose the battery to temperatures above 60°C.

• Do not combine new and old battery groups in series or parallel.

• Do not combine lithium-ion batteries with other battery types in series or parallel.

• Stop using the battery immediately if abnormal operation is detected and seek professional assistance.
