So this would be 12v if connected in parallel.

I reckon that they're wired in two sets of parallel so the voltage is only 6v, but could be wrong. Is there a maintenance manual anywhere?

I guess you mean connected in series?

I honestly don't recall, but I think the unit will not work at all unless all 4 batteries are installed; if it was 2 x 2 sets of 6V (possibly for large in-rush current issues), then it should work with one battery removed, which is easy enough to test.

I had an OZ-7000 (or 7200) Service Manual (in PDF?) somewhere, I will look for it and post a link if I find it.
