The Pololu h-bridge is only one amp per channel. The other is at least rated for 2 amps per channel, but even it isn't really enough -- the motor's stall rating is at 3.3 amps.

Ideally, you'd want a 5 amp per channel h-bridge, but its doubtful that your motors will ever hit stall current running a 2-wheel balancer.
