Bob, and others,

There seem to be 12 cells wired in series. It looks like there is a 
"tap" in the middle between 6 and 7 (two white wire). Cell 5 (counting 
clockwise from the top left) seems to have a temperature sensing element 
bonded to it.

There are leads away between cells 1 and 2 and 11 and 12 (orange and 
black). In fact these look like they might even be the main supply 
leads, making the main supply only 10 cells in series. Looking closely 
you can see  a "+" sign on one of the terminals post of each cell, so it 
looks like the two orange wires are the +ve supply and the black -ve 
(logically enough).

Even when I look at the largest version of the picture, I can't  see how 
the very  first, and the very  last cells are connected. One would seem 
to provide a "below" zero voltage and the other an above Vcc voltage.

Thanks again Bob. I'll go back to the telemetry a see if I make any 
interpretations from this.


By-the-way. Both the comcast mail server Bob uses, and the server used 
by AMSAT have become very fussy about the senders email address. Both 
rejected my initial message (with an amsat.org reply-to address). 
Antispam measures, I guess.
