New to the hobby and recently bought a Traxxas Stampede (electric) I have a Intellipeak Charger 4100 and for now I have one set of Radio Shack GP 3300's.

Since my brain is on complete overload trying to read all of the info available.. and there is a ton.. I would like to thank everyone ahead of time and here are my questions -

1. Where is the best place to learn about charging batteries
2. For a second battery should I buy a 7 cell for it? If so what are some decent ones to look at
3. With no money limit what 6 cell battery can I get that has great run time and won't damage my new toy.

I will probably have some more questions after I see some responses and thanks again
