I would look up "Floureon" batteries on Amazon. The 2S 5000mAh Lipos will be just a little faster and your electronics and drivetrain will be less stressed. The 3S 5000 mAh batteries will challenge your driving skill and push the Speed controller and the drive train to their limits, IF NOT PAST THEM! If your truck has Traxxas connectors you may have to swap up the leads to match these batteries. The Floureons are cheap and occasionally come out of balance, but AMazon's return policy is banging and it shouldn't be an issue.

I own these for my Ruckus Brushless The speed is mental and NOT recommended for lead footed beginners AT ALL!

I'd recommend these for 20+ minute run times They will last a super long time and the speed is more manageable, but still silly fast.... You have been warned :P
