Hi Doug.
I have been told that you can rig a collapsable oil filled bladder that is
hooked to an oil filled battery pod with a hose and it will replace any oil lost
from the pod and the bladder
would just collapse as the oil drained from it into the pod. That
way instead of getting a vacuum in your pod, your bladder would just collapse
according to the amount of oil
it lost replenishing your battery pod oil. Don't know that personally from
experience or anything, but I have been told that.
I'm going to use air equalization for my shallow diving wetsub pod and
motor. The whole oil thing just seems like too much weight and too
messy for my shallow diving applications.
Kindest Regards,
Bill Akins.
