I agree with Sean, it's just lacking some spice! I know you can do much much much better :)
Not bad, but the guitar seems to have too much reverb, the bass is uninteresting. The drums are a bit too low. Look at GREAT battle themes such as Pokemon's, Golden Sun's, Fire Emblem's... Crazy ass bass guitar madness. The drums are well paced. Depending on the type of battle this may be applied with, guitar should be more fast paced, and bass more melodic/complex.
Thank you I will take this advice!
