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
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.
