$10 is a great deal for any battery packs and yeah for just running around they will work great but usually those packs are around $20-30 which are just as expensive as a basic unmatched GP, or CBP pack. the difference in power between a quality pack and a cheap one is unreal though. I remember when I first picked up my KAN 1050 pack for my mini-t. It could do wheelies from a standstill (no backing up) with all stock electronics and gearing. I was sold after that.

Now though.. well its too much. I have a couple of old KAN 1050's and 1 GP 1100 pack. Its running the SPY ESC, TRinity monster machine motor, HItec ESC (don't remember which one) and a bunch of other hopups. If it gets traction it doens't wheelie.. it flips over. lol. ITs a blast to drive on grippy surfaces but just uncontrolable on slick stuff.
