[PSUBS-MAILIST] Battery pods

[Dan H.]

Joe,

On my sub, the forward and aft through hulls from the pod to the hull are the vent pipes shown on the drawing.  The third round piece is actually a solid chunk of steel I drilled four separate holes through.  Each hole accommodates a brass threaded rod that is a conductor.  Each conductor was held in the center of it's hole and the space around it was filled solid with epoxy.  I didn't want any pod gasses seeping into the hull.  And if I ever blew a pod cap off, each conductor is water tight.  The only problem I can imagine is, if I had a complete melt down and the rods got hot enough to melt or burn the epoxy, but if that happened I'd probably have bigger problems to deal with anyway.  

Rethinking...... I think I have six conductors.   I may have put in an extra for a 24 volt tap on the 36 volt system.  I never used it though and one small conductor for water detection in the battery pod.

Dan H,

  I've noticed that K350-006 Battery Pod & Tray, show the main electrical thru hull going to apparently nowhere. I've also noticed Dan H, Scott, and other K-350's with what appears to be a third vent tube just forward of the aft one of two shown on the drawings.


  I'm assuming then that this is a relocation of the thru hull fitting and if so is it fabricated the same as the other two vent tubes, essentially discarding K350-043?
