Re: Batteries
Kittredge's battery pods are external to the cabin, however he does have
vent caps which enter the cabin which I don't fully understand. I guess
he plans on venting the H2 into the cabin during charging and get rid of
it via venting at the surface. H2 production is mainly a byproduct of
charging, but I have heard of instances of H2 release up to 10 - 20 min
after charging. There are H2 chemical catalysts that can be obtained
but I'm not sure of where or how much.
This would be a moot point if gelled or AGM batteries were used, provided
they were not overcharged. Also, the thought of having liquid battery
acid in a sub seems to be to be an accident waiting to happen!
