Green Gears (3.43:1)

I have a set of 3.43:1 green gears. My 2.6 cannot provide enough juice to get them turning. I will eventually do dual batteries, but using only one battery, is there any way I can use this gearset practically? It seems wayyyyy too low a gearing to be useable.

NOTE: if you connect the battery directly to the motor it will spin them up real fast, but the PCB on my car limits the amperage and voltage enough so that my 2.6 can't start up. Also, the mesh is awful in my Microsizer, its fine in the car it came on, the Hot Wheels KIT Racer.
