For a dry cell... I was thinking 18. Will 20 be too thin?

H H, I've got 16 ga. plates in in my 7 plate dry cell.Although I don't have any heat problems I wish I'd gone with 22ga. because the cost of 16 ga. was expensive.I've seen that a good number people using 22ga(and a little thinner) and have good luck with them.My plates measure 10x10 so you can imagine what they cost.

I was worried about flex and the plates somehow shorting in the middle... Mine are going to be 7x7 and there's 18 of them. I think I'll go 20 ga.

thanks,

Did build the dry cell design called tero or other?

I've been using 20 and 22 gauge for all my dry cells. I haven't had a problem so far. I have a 7.5 x 10.5 cell I'm putting together now. I guess that will test to see if it will warp the plates.

I was looking at the tero, but decided on a different plate arrangement. If it comes together I'll post some pics.

How much do drums (musical drum) flex? We are really just making a kind of drum dont you think. I really dont see how plates in a sealed cell can flex much at all. Know matter how thin you make them. So IMO you could go very thin.

Im going with 24 guage = 0.020" for my etectrodes on my 6X6. And plain on experamenting with 0.010" nutral plates. 316L ss



Side question what does the "L" in 316L mean?

I was wondering if the thiner you go with N plates would the resistantnce go down, or the heat go up, or what?
If we try to push 15 amps at 2.2 volts though a 0.02" N plate would it melt like a fuse?
Is it the plates that generate heat or the water solution?
Is there such thing as too thin to drop the voltage?

I cant seem to get my head around these things.
