or should i buy an motor driver ic or 2 and put them in paralell for more current and run off those

or should i use this

thanks,    also , i will be using a 12 v 2000 mah nimh battery


ive read the tutorial on SoR about this but i want your reccomendation for my specific situation

JonHylands:
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.

jailsellgren:
so build an hbridge or buy one
if buy one then post a link to a 5a dual channel one

JonHylands:
Well, this one works, although you would need two of them:
