I would like to create 2 batches for all my courses. But is there possible that students have access only to course which they bought? For this moment when they enrol to one batch group they get access to all courses with which this group is conected.
Ok well that is no possible with the batches as of now .
student will be enrolled in all the course if she is added to batch .This is what the batches made for .
If you do not want this automatic enroll feature and just want to integrate the regular group functionality then you can simply connect the group to the courses in course settings .
