The only way you can do it is by creating an invisible mesh parent which will hold the loaded obj models, since there are some obj models out there that contain more that one mesh, and often they do not have the same scaling factor. After that you should set the scaling of each mesh to  :

parent.getBoundingInfo().boundingBox.extendSize;

Here is an example :

var container = BABYLON.Mesh.CreateBox("ObjParent", 1, scene);
container.position = new BABYLON.Vector3(myposZ,myposY,myposZ);
container.rotation = new BABYLON.Vector3(0,0,0);
container.scaling = new BABYLON.Vector3(myscalingX,myscalingY,myscalingZ);


var OBJ = loader.addMeshTask("ObjLoader", "", "", "batman.obj");
OBJ.onSuccess = function (t) {

	t.loadedMeshes.forEach(function (m, i) {
		m.parent = container;
		m.scaling = container.getBoundingInfo().boundingBox.extendSize;
		m.position = new BABYLON.Vector3(0,0,0); // Put at the origin of the parent

	});
};
