    when i looked at what woudl give the best bang for the buck i found that 6v
    golf cart bateries where hard to beat at about $130 for 200amp/hrs @ 12v (2
    of them)

    you can paralel many batteries as needed... for my inverter bank, I used 8
    golf cart batteries, paired in series to make 12v and then each pair
    connected in paralel (4 pairs).

    to even things out and spread the load/wear, connect them at each end, + on
    one side, - on the other side of the bank

    fuse
    switch

    > Dear all,
    > I'm replacing my house battery bank. After puzzling together the piceses

    > I do understand that e.g. 2 same type batteries connected parallel works
    > fine. But how about 6? Any of You have this type of arrangement? Is it
