48V 100AH 19”Standard Cabinet Telecom Lithium Ion (LiFePO 4 ) Battery Pack 482.0mm X D 540.0mm X H133.0mm

  • Product Overview


The 48V Lithium Ion Battery Pack is mainly working as 48VDC backup power source, and it consists of 15 cells of Lithium Iron Phosphate Battery Cells connected in series and telecom specialized high performance and high reliability Battery Management System (BMS). The battery’s +/- output terminals are connected to the +/- terminals of rectifier. When the mains supply is normal, telecom equipment is powered by mains through rectifier and battery pack is also charged through rectifier; When the mains supply is outage, the 48V lithium ion battery pack is supplying power to telecom equipment without any time-delay to ensure telecom equipment is powered without any interruptions, until mains supply resumed or protective power cut-off by BMS due to over-discharge protection activated automatically.​


  • Features and Benefits​
  • Host computer control function

1) Through the host computer to set the protection parameters such as overvoltage, undervoltage, overcurrent, overtemperature, under temperature, short circuit, as well as balance, sleep, capacity, and other functional parameters and various alarm parameters.

2) Supporting monitoring of battery pack related information, battery status information, etc.

3) Supporting storing and exporting related data

4) Supporting writing barcode

5) Remote Control and Telemetering


  • Serial port upgrade function

The management system can be upgraded via the RS485 interface.

Communication Protocols

Default setting protocol with baud rate 9600, and other protocols are also supported.


  • Charge current limiting function

After the current limiting module is assembled and enabled by the host computer, the charging current limiting function can be implemented. The current limiting mode is current limiting after charging and overcurrent; the current limiting value is 10 ± 1A.


  • Anti-reverse function

Battery has Anti-reverse circuit. After the system is powered on, the protection board will be burnt due to the reverse connection of the battery during parallel installation.


  • Parallel communication function

The parallel communication function can be realized through the RS485 interface, and it can support up to 6-digit DIP switches (typically 4-digit DIP switches) for setting addresses when communicating in parallel. After parallel connection, the battery pack data can be monitored cyclically through the parallel version of the host computer.



  • Data Storage

Battery supports no less than 500 battery status data storage functions, protects all data and regular historical data during all state transitions, and stores 1 historical data every hour.

Basic Parameter

Item Settable Detailed Information Default Setting Value Remark
(Yes or No)
Charge Current Limit No Limited Charge Current Value 105A Acceptability range:105 ± 2A
Yes Method of Charge Current Limit Overcharge activates current limit N.A.
Sleep Voltage Yes Sleep Voltage Set Value 3.30 V Acceptability range: 3.3 ± 0.02V
BMS Power consumption No Internal Circuit Power Consumption at Mode 1 – Fan is not activated or for natural cooling model with heat radiator ≤ 40 mA N.A.
No Internal circuit power consumption during sleep ≤ 500 uA
Charge Balancing Yes Balancing Activation Voltage Value 3.40 V N.A.
Yes Balancing Activation Voltage Difference Value 50 mV
No Balancing current 70 mA
Full Charge Setting Yes Constant voltage value 54 ± 0.3V During constant voltage charging, when the overall voltage is greater than the constant voltage and the current is less than the constant current value, the BMS will assume that the battery capacity is fully charged and the charging MOSFET will be cut off.
Yes Constant current value 5.0A
Standby Time No Interval days of forced recovery charge after overcharge 0 In order to ensure the battery capacity, after the battery over-voltage protection, the battery will be forced to resume charging after a fixed time; when the time is configured to 0, this function does not work.
Under-voltage OFF Time No Discharge MOS turn-on interval time after undervoltage 0 In order to be compatible with the traditional lead-acid charger charging method, the BMS periodically closes the discharge MOSFET for about 7.5 seconds after undervoltage protection, so that the charger detects the battery voltage and turns on the charging. The interval period of the closed discharge MOSFET can be set. When configured to 0, this function does not work.
Capacity Setting Yes Full capacity setting 100Ah N.A.
Yes Residual capacity setting 50Ah
