Without even seeing your drawing, I'm wondering if you have considered
pressure compensating the batteries using oil. Certainly, this can make
maintenance and charging aspects more complex. On the other hand it could
simplify a lot of other aspects of your design, and keep overall weight to
a minimum.
Your 150 psi max pressure implies that you are going to 300 feet depth.
Sounds awfully deep for an ambient sub. Or is that 150 psi to give a
safety factor of 2?
I can't remember what drawing program produces files in a .dwg format.
What drawing program did you use?

Subject: [PSUBS-MAILIST] Battery Box Help
I was hoping there is someone on the list that could help me out. I am
trying to design a battery box. I'm not an Engineer so I'm not sure if a
design I have would stand up to an external pressure of 150 psi max.
This will be placed into an ambient sub. I have the box drawn as a 3
view. The file format is .dwg. What I'm trying to come up with is a box
to hold 4 type 27 batteries in as small a package as possible. If you
can help I would greatly appreciate it. Just let me know and I will send
you the file.
Regards,
Dennis
