Yes the battery is a MaxAmps 3s2p 6000mah pack. The tires are Masher 2ks and agreeably not the best for a speed run. I just wanted to see what I it would do. I know that there is a lot left in it even in this truck. I could probably pull a 22-23t pinion and mess with the settings on the Mamba to really max it out. I may attempt to get it over 60mph and call it quits.
