purchased two 3300mah batteries at Radio Shack. Also bought the charger they had there. It's a simple kinda charger... plug the battery in, charger in and when the red light goes out it's charged...

MAJOR DIFFERENCE!

Truck ran almost as fast as it used to... very impressed. I'm gonna try running a second battery mainly just for longer runtime. I had a pretty impressive runtime with single battery... double should be sweet.

Much thanks squeeforever & everyone else who responded.
