LFP 48V 50Ah Solar Power Energy Storage Battery

Polinovel 48V 50Ah lithium battery has built-in BMS battery management system, which can manage and monitor cells information including voltage, current and capacity. What’s more, BMS can balance cells charging and discharging to extend cycle life. Multiple batteries can be in parallel for larger capacity and longer power supporting duration requirements.
Availability:

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.

4850-3U-1

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.
