I want to add 2 6-V golf cart batteries for my house system, and
cannot find the ones that Walmart or anyone is selling for less than
$75 dollars. (I cannot find the $75 ones)

I will only be using for a year (one loop) so have no need of the $400
ones.

Any suggestions (and link) would be well appreciated. I keep reading
about them, but cannot find any!!

thanks
