Home-brew battery measuring station

battery tests would be awesome.is there anyway to use a fluke meter?not sure how many amps they can measure.what about using automotive battery testers for the amp draw?some good ones use carbon piles.our high school had one that was adjustable.just some thoughts,i do appreciate the fact that this all is being done on a slim budget.

also,since electrical minded folk might read this,how hard would it be to build a non adjustable output driver for a brushless motor?like to power a motor on a dyno,or a starter box?
