If you are using lithium batteries with your solar power system, you will need a lithium battery compatible solar controller.  Lithium batteries require a slightly higher charging voltage than standard lead acid battery solar controllers which often do not have the option to select lithium battery type.  A standard lead acid battery solar controller may reduce the cycle life of your expensive lithium battery.
