[PSUBS-MAILIST] battery box

[Alec Smyth via Personal_Submersibles]

If I understand correctly the magnets are strong enough to hold against
things like road bumps and of course the thrust produced by the motors when
in use, but weak enough that blowing MBTs would pull them off. But what
about the cables? In the Deep Workers those all go through a hydraulic
guillotine.

Thanks,
Alec
