This then slides into the tube, giving excellent support for the batteries, plus I left the magnets in place. It would be interesting to see how Frodo did his installation, especially the tank, because one litre is the minimum size tank for the X45, in my opinion. Your solution is equivalent to a full size new tank install, from a engineering point of view!!.
