sorry Joerg...
Look at Nigel's web page he has a breakdown of the cells.. I have done the same thing fro my own uses.. The resister values vary depending on the type of cell.. Higher output cells just use a different main resistor to change the voltage range..
Hi Joe,
I finally got my lazy ass around actually analysing the board as you suggested, and found the circuit similar to what Nigel posted. It has one more resistor. This from a AP Cell (S/N 658917, board has S/N B77102 REV.0).
So the effective internal load is basically more or less the same as Nigel suggested.
Why the heck is the 10K externally then needed?
thanks guys
Joerg
