This may fit the super tune thread but it has to do with batts so here it is. Not a big deal but I ejected some batteries last week in an "incident" and think I have a good cheap solution. I stopped at the LHS and picked up a piece of balsa approx 2.5x24x1/8. As luck wood have it the width was perfect for the SV's existing battery trays. I cut them to legnth and then cut some reliefs in them so the straps would not interefere with how they rested in the hull. I then epoxied one side and let dry. Then I did the other side and set them in the boat with the straps in place. I think they are going to be pretty solid.
