Melons posts were spot-on in my opinion, from a technical stand-point. Pat, there is ZERO reason to have any charging logic on a NiMH battery pack. That is only needed with Lithium-Ion cells.
In this pack, the thermistor is there to insure that the pack does not go into thermal runaway because of a shorted or reversed polarity cell. The additional monitoring points can also be used to detect deficient cells. Ideally, they would also be used to balance-charge a pack of this size as that is the worst issue with a large number of cells in series. They can also be used to turn off the radio if one section of the pack becomes sufficiently more discharged than the other parts.. As for price.. I think $25 is fair for a pack of 10 cells. I initially thought it was only 5 cells after looking at the web page. However, I would hope they are high quality Japanese cells and not the often inferior Chinese nonequivalents.. I will certainly buy the accessory pack as soon as it is available. I can never have enough remotes around the house. However, it will likely be the last time I buy a pack and will instead opt to build my own. I have found packs of this nature very disappointing in recent years. I build my own packs for everything. I even converted my Scooba and Roomba to Lithium-Ion. I can usually build the highest quality pack with much stronger cells for 1/2 to 2/3 the cost of a retail replacement. Of course, you have to enjoy playing with electronics first.. As for MM's comments in this thread, I found them to be neither Bully-ish or Jerk-ish, but I have never seen any of his other threads.. I would love to get a look at a pack though. This is the one suck-point of the radio. It's assembly quality is too good for me to take it apart and try to reverse-engineer the charge circuit to figure out the wiring for the pack. Looking at the thing I have to wonder if logitech kidnapped an Apple designer. Don't mess with a good thing is what I keep telling myself...
