Telecommunications base stations are facilities used for wireless communications, such as mobile phone towers, and they are responsible for transmitting and receiving wireless signals that allow people to make phone calls, send text messages, and use mobile data. Therefore, in order to maintain the normal operation of a communication base station in the situation of main power supply failure or power outage, the backup battery plays an important role.

In this project, we provided 6 pcs 48V600Ah lithium battery modules(EV48600-T) connected in parallel which can provide a backup power supply for 60 minutes for a 25KW system, ensuring that the communication system can be maintained without shutting down when the main power supply fails, avoiding a large amount of economic losses and gaining time for power repair.
