A few months ago, I purchased this unit from Renogy.
Me and Renogy Help desk have been swapping emails many times. The solution they give is the same every time but it never works.
My issue is I cannot get the battery type button on the controller to get up the screen that lets me select the type battery to charge (I have the standard RV battery I think called the flood type. When I hold down the battery type button all it brings up is a flashing 14.4 screen.
My question is has any of you all had issues getting to the battery type screen with this Renogy suitcase unit and if you have a solution.
Many thanks.
