ok so I have been doing lots of research lately about most efficient drycell configurations and this it what I come up with for my first attempt..
Now nothing is set in stone on this plan since I am new and I value your imput. so please comment both possitive and negative will help me with my overall plans..

this is not to scale, but the plates will be 7x13 so I will be left with 6x12 surface area after gasket..

holes at the bottom will be staggard

now this is my main question I have done lots of reading about people installing kitty corner (2) tabs per plate since these are gonna be large plates I decided to go with three power tabs per plate as indicated in photo. is this a good/bad idea, overkill. bottom line is will the three tabs make it more efficient or not??

I have not decided on my cell configuration just yet since I have not recieved my new altinator and deep cycle batteries, but it will either have 5 or 6 neutral plates depending on voltage...

Im also contemplating setting it up as a 120v ac 61 plate design using a rectifier. thoughts on that also would be helpfull

thanks again everyone for all your great support and inspiration...
