Part 1 – Safety & Warning
The NPFC series LiFePO4battery system installation, operation, maintenance should follow
important recommendations in this manual:
The equipment shall be installed by the professional training staff
Battery maintenance should be carried out by the experienced professionals and aware
of the preventive measures on the potential harm of the battery.
Note: Be care of the risk of electric shock for large current in case of battery short
circuit, pay attention to the following points during operation
Remove watches, rings or other metal objects
Use tools with insulated handles
Do not place tools or metal objects on the battery
Do not direct access to the battery system to the mains grid power outlet
Do not put the battery system into fire, do not use or storage the battery near to the
high temperature source
Do not use liquid or other objects placed into the battery system.
Do not open or cut the battery, not to hit, throw or step on the battery
Using special communication between battery module and power plant to charge
battery
Be sure to subject to charge and discharge parameters setting in this manual
The output interface of the system is still voltage when grid power cut, avoid electric
shock or short circuit when operation
Please check if the box is damaged. If damaged, please immediately notify the supplier
If you find leaking liquid or white powder residue on product, prohibit operation.

Part 2 – Product Introduction
2.1 – Overview
NPFC series battery system is 48V system for communications back-up type LiFePO4(lithium
iron phosphate) battery products, the system uses the advanced LiFePO4battery technology with
the benefit of long cycle life, small size, light weight, safety and environmental protection, and
has a strong environmental adaptability, it is idea for harsh outdoor environments.
The system also integrates a smart battery management and monitoring module, support
for remote centralized monitoring and remote battery management and maintenance, to meet
the requirements of unattended. Therefore, the NPFC system can fully meet the backup power
supply requirements of the access network equipment, mobile communications equipment,
transmission equipment, micro base stations and microwave communication equipment.
2.2 – Working Principle
The NPFC battery system mainly includes Fe lithium battery pack, battery protection, cell
balancing unit, monitoring module and charge-discharge management module for optional. Its
schematic diagram shown in Figure 2.1

LiFePO4Battery Module for Telecom Operation Manual V8.3 2016
NPFC battery working principle:
DC power input charge and discharge management unit after filter, DC divided two circuits,
one circuit directly supply the load, another circuit to charge Fe lithium pack. When grid power
on, the system supply the loads and charging inside Fe lithium batteries; When grid power failure,
Fe lithium inside system supply DC power to the load, to ensure uninterrupted power supply as
power system.
2.3 – Battery Management System (BMS)
Smart BMS technology is adopted for battery modules of NPFC series to assure smart
automatic management for batteries. Features of BMS are shown as below:
There is a centralized monitoring unit in BMS. Functions such as remote measurement,
remote communication, remote controlling are available. Battery modules can be
controlled remotely by staffs in control center. NPFC series are in line with the
requirements of the development of modern communications technology.
It is combined by technologies of power source and computer. Parameters and status
of rectifiers and AC/DC distributions can be detected and controlled.
Excellent electromagnetic compatibility. BMS used for battery modules of NPFC series
can comply with the outdoor power plants during operation, no interfere with each
other.
BMS can provide protections against overcharge, over-discharge, over-temperature,
overcurrent, short circuit, etc., to assure reliable safety and operation life.
With patented cell balancing technology, BMS provide high efficiency for cell balancing
and prolong system operate life.
Configuration flexibility, support parallel connection expansion
