I am also debating on going with lipo's and a brushless set up. I am curious as to how they plug in? from what I can tell the orion don't have a built in plug. Looks like the Maxamps have a plug but also have some other type of plug. Can someone let me know what that is for? Maybe someone can post some close up pics of their set up. Call me an idiot I guess. I have always direct soldered my stuff so I am new to this whole deal.

An even cheaper choice is the truerc.com pack
You can purchase a 7.4 volt 8kmah 10c pack for $75. mamba on 7.4 volt packs will never come close to 80 amps of current. The reason they are cheaper is because they are a 10c pack and not a 20 c pack like the max amps packs. Now, for chargers I still believe that the astro flight 109 w/ a blinky is the best lipo charger on the market. However, the A123 batteries are also starting to grab my attention. They have the same charge and recharge qualities however they can be charged at a 5c rating. This means that you can charge your pack in under 15 minutes. You also don't have to worry about over charging them either. The a123 cells are all 3.3 volt 2100 mah cells which does make for a slightly differant pack. Perhaps if you plan on running 1/10th scale truck you could just run a hotter motor. The norm is a gtb 6.5 or mamba 5700. However a 3.5 or a 7700 would probly lay down similar numbers on the differant voltage. The a123 cells can also be discharged at a 30c rate. If I knew more about them I would personaly go and tear down a dewalt battery pack and get 8 cells for $100.

I would personally go with a maxamps 8000mah battery pack. From what I read when I was going to do lipo (couldn't because of race rules), for the money you spend, you get a pretty good quality pack, and LONG runtimes. People are using this type of pack to run with nitros in there 20+ minute mains.

As for chargers, I was going to use a MRC 989 and those who I know have this charger and do lipos like it.

You will also want to pickup a liposack or battery bunker to safely store you packs, and probably a balancer too.
