Product Description

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.
