RE: [PSUBS-MAILIST] joe's electrolyte plumbing

Probably all the work I would have to do trying to make something like that work would cost more that if I had just used gel cels ;) I'll probably end up having two different battery modules, I'll start with the basic lead acid and I just won't be able to flip. Then if I get rich I'll build another module that has gels .

Lead acid batteries have a space below the plates where they collect the waste that sluffs off the plates over time and I don't think that would be too good for the electrolite if it were stired up. But maybe you just filter it out from time to time. I'd think you'ld need to remove all of the air so that the plates are not exposed to the gas when they are inverted. Without gas present you elminate the chance for an explosion due to a short. Your plumbing system will need to hoses big enough to carry bubbles easily. A common electrolyte reservoir on top of the batteries would need something like a weighted fuel line used on gass weed eaters. That would prevent gas from returning to the batteries when the system is inverted. And then you would need a pressure relief valve connected to the reservoir that had a float on the end of it's line so it only vented gas. If the reservoir had a bladder so it was ambi! ent pressurized then I don't see why you would need to bother with the mineral oil. The oil would make checking and maintaining the plumbing system a lot more work.

That all sure does sound like a lot of work. I was going to go with lead acid until I built my battery housing and then learning that I accidentally used the measurements for the smaller gelcells. Gelcells have a big price tag, but perhaps it would be easier to fine something else in the budget to cut. Maybe you can forgo shoes for the children?

On a side note, we have the engine installed with a factory built oil cooler that did not explode. :) It's all hooked up through the gear box and turning the jet pump and has the water tight drive shaft housing in place. We only tested it at low RPM, but so far so good. It sounds wonderful to hear that engine.

Good Luck to Ya

Hi All,

            I've been thinking about how I could turn a regular lead acid

battery on it's side with out having the electrolyte come out into the

surrounding mineral oil.  What would the effect be if all of the cells of

the battery were plumbed into a manifold and ran to one central point?   As

long as the hydrogen gas would have an avenue to travel out to the end of

the piping system wouldn't that satisfy the integrity of the battery?  



If whoever answers this could start a new thread name it would be greatly

appreciated, I don't seem to be getting my own posts back, thank you .
