Brent Regan said: I have been using a similar setup using two 20 AH
Panasonic batteries LC-X1220P for 13 years. I just installed my 4th set
and have always replaced on time rather than on performance. Finally,
remember to always disconnect the battery ground first and reconnect the
ground last.  This will minimize the opportunity to short (and vaporize)
something valuable.  I learned this lesson after copper plating my thumb
and getting a nasty flash burn.

Brent, thanks this is exactly what I was looking for....including the
picture. I anticipated I would have to custom make battery terminals.
Again thanks for a good plan. I have always been amazed that one can
copper plate almost anything with a little current.<g>
