Thank you all for the input. As always, I can trust that this group has a wealth of distributed knowledge.
Allow me to respond to a few of your suggestinos and comments. I did look through my P200 Radius manual (don't have it handy or I would write down # of manual) and found a small section in the back describing the theory of opperation regarding the bank charger. There was also a schematic and expoded diagram. It was very enlightening. The six slot charger is much more complicated than I thought. I am glad I took digital circuits or else I would have been lost. Thank you Mike for your comments on Bob's article. I had a feeling that was the case. As I have researched, experiemented, and learned a little more I came to the same realization. Either you could modify the charger or modify the resistor and thermistor in the battery. I guess manufactures have finally picked up on that and begun to install different components in the packs. So, this raises another question. Monitoring battery temperature while charging. I guess the IR thermometer would be ok but I immagine the batteries inside the shell would be a bit hotter than the outside of the case. What would be a better way of monitoring battery temperature in order to determine if the battery was charging properly or not? I guess I will leave the charger alone for now since the circuitry seems different enough from the desktop fast charger that the same modifications can't be made. Also, as stated above, the modifications may not be necessary at all. Thanks as always.
