@Fran-Diox I tried doing it and got it working with a glitch on scrolling enabled that messes it all .Here is the code

  <ons-carousel fullscreen swipeable auto-scroll overscrollable id="carousel" direction="vertical" style="overflow: hidden;">

    <ons-lazy-repeat id="infinite-list" style="overflow: hidden;">
    </ons-lazy-repeat>
  </ons-carousel> 

and the JS

  var infiniteList = document.getElementById('infinite-list');

  infiniteList.delegate = {
    createItemContent: function(i) {
      console.log('Current item is ' + event.activeIndex);
      return ons._util.createElement(
        '<ons-carousel-item style="background-color: #085078;">Item ' + i + ' </ons-carousel-item>'
      );
    },
    countItems: function() {
      return 10000;
    }

  };
  infiniteList.refresh();}

Is there any way to get infinite scroll on carousel ? appending is not working on it.
