Benny, when are you gonna use the "search" button? We don't mind answering your questions, if you simply scrolled down you'd see that we answered it twice already this week.
I like the Venom 3600s, that's all I use. I try to buy the ones with the "noodle" wire because not all the battery packs are the same length so I use the shorter ones in the Tigers and the limber wires help. I get 3+ hours on them. The 3300s can be had for a little bit less, but I wanted all my tanks to have the same juice.
Now, your next question is about a good battery charger right? I like the DuraTrax Piranha. It's about $50 at Tower and has an LCD screen.
