[RE-wrenches] FX2000 / Trojan battery question

There were originally 8 batteries in the set. 4 were just pulled out and the
remaining 4 are temporary till the replacements arrive. The loads are 75
watts constant. But good point, this is a smaller bank now. I will put 4
more loaners in there to see what happens.
The 4 batteries are strong, so i didn't expect a battery problem and it is
getting the solar input daily also. As long as the sun holds out! Were
entering dark season up here.....

I had forgotten the outback habit of strange error warnngs.

Thanks,
Bob
