Re: Looking for a desktop power backup

biggest minus is floating batteries at over 14,4V per 12V battery

14.4V ?!?!

I think that's OK for charging gel batteries, but too high for float. Would it be possible to adjust it?

Likely is, but getting the info is another story. I don't know what it is about the UPS industry, but I haven't found any of them that are willing to give any info on their units. I did get schematics from one company a while back, but I had to sign a NDA to get it.

Probably changing a resistor. The board is absurdly complex.
A simple solution is to add diodes.
