I recommend that you try B&T Batteries http://www.rc-aero.com/biz/bandt/.
I just received my order of 2400 yesterday, placed the order on Monday. I have been ordering my batteries from B&T for the past 2 years and their batteries are as advertised.
I race strictly stock so 2400's more than meet my need. In the past, I bought several sets of the older generation (Panasonic) 3000 batteries, and was very dissapointed with their life span. Even using the approved/suggested charging methods the 3000 lasted about 1 season. The 2000's that I bought years ago lasted 2 -3 racing seasons. Granted the 2000's were only good as practice packs after the 2nd season, but the 3000's were completely gone after a single season!
I understand that the new generation of 3000's are better, but I'm not ready to jump on to that bandwagon yet. The care and feeding of NiCd's is easier, and I have better results with them. Besides, I don't really need 3000's for racing stock. Give B&T a try, they are a well kept secret!!!
