I just ordered a new pack from NoBS. http://www.hangtimes.com/nobsbatteries.html The website is great for learning a bit about receiver packs (what to look for, what to avoid). I had a question for them about my purchase, which I sent off at 6:47pm tonight. I had an informative reply from the owner at 7:09pm, which answered my questions and recommended a battery for my purpose.

NoBS has had a really good reputation, and I can see why. I'm anxious to get the pack, and even more anxious to put it to work!
