The communication facilities of telecom operators tend to be integrated, smaller and lighter. That means more business
facilities are to be installed in a limited space. This has prompted higher requirements for the temperature range to be
gradually or have been started seeking and studying the new backup battery solution. Based on its technical features as
high capacity, high voltage and free of pollution, the lithium-ion battery is widely concerned by people with a rapid
development stance. It will be the first choice for the high-requirement backup battery solution.
Polinovel PL48 series lifepo4 lithium battery system is mainly used for the backup battery of the telecom communication
industry, especially suitable for application scene of high temperature, limited installation space, restricted load-bearing
and long cycle life.
Features
● Lithium-ion battery offers extended cycle life and good safety performance.
● Embedded BMS offers voltage, current, temperature protection, and alarm functions.
● 4 remote functions which can communicate with far-end central control center by computer management.
● Real-time monitoring and control of various parameters and status.
● Secondary protection to cut off the support from the battery to protect the battery service life.
Wide Applications
Polinovel PL48 series lithium batteries can be used to support reliable power for various applications, including:
Base transceiver station, Wireline outside plants, Central office, Communication equipment, Uninterruptible power
supplies, Telecommunication systems, Switchgear & Control back-up power, Fiber-Optic access network backup power,
Solar wind power system, Other standby power supplies.
