1. Overview

The LSUM YJ Module has high energy and low ESR to meet energy storage and 

power delivery requirements. 

The cells used in the module have 2.7V/3.0V maximum voltage rating and are 

connected in series to get higher operating voltage of modules. To meet the long cycle 
life requirements, the cells operate under rated voltage. In addition, all the cells are 
balanced by balancing circuit connected parallel to each cell.
