I had an adjustable carbon pile that I could pull 0-70 amps from continously. The thing was fan cooled, which was a good thing, as you could have toasted weenies on the thing when it was really cookin.
Pat, if I have a large battery pack to cycle down, & sometimes even my small ones, I just put a plane in the airplane cradle, & hook up the watts up meter, plug everything in & set the throttle to where it's pulling a low amp draw. Depends upon the motor system, something big that can take 50 amps or more, I'll run at a 10 amp draw rate. Then from there I just keep track of the amp meter while I play with other toys. Run it down to 1/2 or the rated capacity for storage & if I'm doing a full cycle, down to 3 volts per cel.
