Psub stuff. The whole rig was made right in the shop. Lot of talk about this battery and that battery these days, but those fourteen two-volt cells in a few gallons of oil were, and continue to be, very hard to beat for practical use. We never, ever had a problem while I was there. And only serviced them annually!

It’s a pretty sweet set up.

Exactly the method used
on the JSLs for the battery box release. The cam holds a suspension rod under
compressive tension. Meaning the battery/chassis connection is strong and
immobile. When wound open, the hook is rotated open side down, guaranteeing release.
Back of box suspended on bronze bushings. The front is released, battery swings
in a short arc down and aft and AWAY you go. Realy good solution. Press the weight tight to the hull.
