 * 
 * # Description
 * This application is device for 2-series cell lithium-ion battery.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device coummunication and enables cell balancing.
 * 
 * ## Application Task  
 * Checks if overvoltage is occured and disables cell balancing. 
 * If overvoltage doesn't occur it enables cell balancing.
