I've already considered the FIRST battery, but it's much too large for the application.
What kind of battery might be best for this use?

Craig,
This is one of those 'not enough info' questions. The amount of load on the motors is important in determining the battery requirements. The Globe motors will draw very little current compared to the CIM under load. Since all motors will be running full out for two minutes, and under load, it is likely a gell cell in the 7 to 10 amp/hour variety should work. Why not build the device using the robot battery and see what your results are under test. You may find out that the demand is such that a higher capacity battery is just what you need in terms of recharge and length of usage. A lower capacity battery might work but will reguire a recharge after only two or three, two minute runs. The robot battery might give you more runs and a higher reserve in case of random high loads.
