<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif";color:black">I was thinking of testing both my battery pods to 600’ before I weld them to the hull so that if there are any issues with leakage I would still be able to get them on a lathe.
I added two vents per pod with O rings so that I can push/suck air across the batteries while charging so there are a couple of more places for leaks to occur. I did the calks' and they weigh in at 295 LBS. each dry with a negative displacement of around 30
lbs. I was hoping that they would barley float with no batteries in them so that I could weight them just slightly negative for ease of launching and retrieving but that’s not the case. I need to come up with about 30 lbs. of positive buoyancy and don’t have
any syntactic foam so I figured I could strap some 4” X 4”, on them to achieve that. This may be a dumb question but does anyone happen to know the per foot buoyancy of a 4” X 4” in sea water? If not I’ll head down to the ocean and start testing.<o:p></o:p></span></p>

that.<o:p></o:p></span></p>
