Good idea Chip.
I believe what you just described is exactly what
Rick and several others are doing. Some of them are using multiple regulators to
make sure
they have enough flow rates for the accents and
decents. I will also probably use a regulator for equalizing my
motor's housing against the outside water pressure.
But of course my reg will not be constantly flowing
air as some of their hull systems will be. Once my motor housing is equalized
the reg will shut off until there is a pressure
differential again. That is also the system I
prefer for an ambient hull rather than a constant flow system because it doesn't
waste as much air. It cuts off once equalized and doesn't kick
back in until there is a pressure differential
again. That way of course does not replenish the O2 inside the hull as well
as the constant flow system does and you have to
either use a scrubber, regulator, or surface when the air
starts to get stale. Still you waste less air than
with a constant flow system. I could use the same scuba regulator system to
equalize my battery pod, but I think the strength and thickness of my pvc
battery pod will serve as a pressure hull
for my batteries and will not require equalization.
It will require a bit of ballast though to overcome the air voids between the
batteries.
