[PSUBS-MAILIST] Battery off gassing

[hank pronk via Personal_Submersibles]

 Brian,before you fill the other motor with oil, check the rpm if you have a rpm gauge.  Then check it after filling to see how much it drops.Are you going to remove the oil filled motor and check the brushes and comutatator to make sure it is all good.Hank

 Hank,      Just waiting for the batteries, which is good, allows me to sew up little loose ends.  I've been running the motors with an external cheapo battery bank.  My port side motor had been sitting in the wd-40 for 3 or 4 months and ran with no problems ! Brian

 Brian,I was under the impression that AGM batteries did not.  Your probably right though and in my case the batteries are not sealed up in a compartment and are well vented.  You must be getting real close to having a working sub.Hank

 Hank,   I think all batteries will off gas hydrogen to some degree. Brian

 Brian,Where are your batteries going to be, I am assuming in the horizontal tube.   When you say of gassing, I assume you mean Hydrogen.  The Hydrogen is going to float up and keep going up out the hatch isn't it?  I think the venting systems are for pods or in my case in Gamma where the batteries are sealed in a small  area.   It is wierd they off gas, what did you buy?Hank

 Hi All,                The batteries I'm getting will off gas while cycle charging at a rate of 23 cc/hr per battery ( I will have 8 - 6v batteries) , the discharge rate they say is zero  .  Does anybody have a good air flow system they would recommend while charging?  Brian_______________________________________________
