    Description : This file	has	to be edited before	compiling and contain
                  the battery specifications.
                  - Battery Type : Define the battery type to be charged
            	  - CELLS : Number of	cells in the battery pack
    	          - VOLTAGE_STEP : ADC step VOLTAGE according to ADC input
    	          resistors	at voltage measurment
            	  - CURRENT_STEP : ADC step VOLTAGE according to resistors	
				  at current measurment
                  - CAPACITY : Define the battery capasity
            	  - Cell_VOLTAGE : Define the cell voltage for LiIon 
            	  battery
        		  - NTC table : Number of	ADC	steps according	to 0.5 
        		  celcius at the NTC measurement. Starts at	step 400 and
        		  ends at step 675 Se further details in the documentation
