Has anyone tried to make a cap for the top of a battery with a rubber top to hold in oil. So instead of building a box around the battery, simply encapsulate the openings of the battery body. Again this is in an effort to keep the sub light.</div><div id="yui_3_16_0_ym19_1_1479041151307_8503">Hank</div></div></body></html>
