Thanks alot to everyone who replied (especially Metalman). I just ordered a pair of 2s1p 4000mah LiPo packs from Max Amps. I also got the Hyperion balancer and charger, because Mike doesnt have the charger in stock, and tower wasnt enough of a price cut to be worth the extra hassle of placing 2 orders ( and probably not even enough to cover paying 2 shipping charges). I also have a 8L/ 9920 combo, heatsink, ubec, and Strobe slipper setup on their way from Mike. My truck is about to go from fast to insane. Thanks alot for all the help.
