The amperage does vary a lot depending on electrolyte concentration and type, number of plates, separation between plates, amount of electrolyte, plate surface, etc. However, I think I'm going back to 5-cell configuration, even though it uses more voltage than I really want per cell, because the 7-cell requires a very high electrolyte concentration to generate the necessary amperage, and I hate using such a caustic chemical in such high concentrations. I'd like to use less than 30% by weight as it has been suggested by many.

hydrotinkerer: the intake at the bottom doesn't work because the pressure in the electrolyzer makes the water go back to the container through the intake hose too, eliminating the circulation effect. Just by putting the output hose of the electrolyzer through a bubbler causes enough pressure in the electrolyzer to push the water in the intake back to the container, even with the intake at the bottom. Have tried that....

Any other suggestions, or corrections if I have done something wrong, are VERY welcome. For now, I'm setting up to use a pump.

Thanks for all the comments.

Once you see this design you will understand what I was trying to say, sorry if I wasn't clear enough. I did not notice before that you used clear plexiglas for end caps. What are the cell measurements?
