Bill,
The box frame idea is reinforcement, like ring stiffeners for a cylinder, only moreso.

Hi Vance and Adam.
Could either of you tell me what is the purpose of isolating the batteries from each other into seperate compartments?
I was thinking about what the reasons could be and I could only come up with two possibilities. Is it because, if there
was a leak in one specific spot on the main box, that only one battery would be contaminated by sea water leakage
and only form enough chlorine gas as one battery could make? Is another reason to contain any hydrogen gas formation
in seperate compartments for some reason? That wouldn't seem to make sense though because if one compartment
exploded and the others were seperate but contaminated with hydrogen, they probably would rupture from the explosion and blow up
also. Or is it some kind of structural reinforcement thing? You are talking about a battery box inside the sub's interior not outside it
correct?
Thanks,
Bill Akins

One box with dividers? That's the way the Delta runs. Each pair of batteries (8 220 amp 6 volt Trojans) is in a separate, um...compartment, I guess, at least from a structural angle. The box lid is strong, gasketed and bolded with a whole box full of 1/4 20s, but is not structural per se. Is this what you're thinking?

Vance,
In order for that kind of battery box to work structurally, each battery has to have its own box.
