Something I've discovered as I've set up my electrolysis bath, is the more surface area you have, the better your battery charger will work. I have a Schumacker I use, for instance, and when I first started I only have one anode (a rusty saw). So even though I had it set to ten amps, it was delivering three to four to the water.
Then I went to Dollar Tree and bought some dollar cookie pans. Using 12-2 gauge wire, I hooked the saw to a pan and sit it up on opposite sides of a trashcan. That increased the ampage to about 4-5. Finally, I switched over to two dollar pans, bringing the ampage up to the full 10, which based on its setting was what it was supposed to be delivering in the first place.
Lesson learned (for me at least) is the best metal for electrolysis is not necessarily the thickest, but one that covers the most area. These sheets are super thin, but take up a lot of room. I sand them down to remove the coating.
I also learned that just because you have a battery charger set to a certain ampage, doesn't necessarily mean that's what you're getting in the water. You have to play with your system, and see what works for you.
Hope that helps!
