1. Telecom back up power System :


The system needs to provide the rectifier power module the power while charging the battery system toback up power  grid in case of power failure, provided by back up power series battery power systems, DC power systems to ensure proper operation, uninterrupted power supply function.


Power with rechargeable function, when the battery voltage is too low battery power management module BMS cut off the power supply circuit to protect the battery life.


2. Software and Communication Module


RS232 communication 


Cell system using the RS232 interface to communicate with up system, the battery system transmission parameters, and alarm status information, protection information, and other parameter settings of the battery module, RS232 communication rate of 1200bps for general use.
Only when the DIP switch is set to Pack1 (Master Pack) mode, RS232 communication module to be



RS485 Communication RS485


When the battery pack in parallel, main battery pack can communicate via RS485 interface,which saw main battery and other battery pack information from PC.
