Yes, if I have to kludge together a charger for a drill battery or some 
such I use a variable bench supply and measure the drop across a series 
resistor and tweak things periodically.  This thing doesn't lend itself 
to measuring the current and it would be out of range for my old Fluke.

I took the cover off and checked, it was up to 26.9 volts and dropped 
back to 24.6 after a bit connected to a 21" tv/cctv deal I have to help 
the feeble of eye read text.  It's good, and I found an item in the 
configuration I could set to make it ignore the [false] low battery charge.

I want to try "nut" also and see if it works any better.
