Re: Figuring out current density
With a 14V25A PS you may need to drop to 5 or 5.5 ASF. The 14 volts calculates to a max CD of 5.6 ASF. Depending on your setup, tank temp, aluminum content in the electrolyte, you may be able to get away with more but I would start out at a 5A CD and see what the peak voltage is for a run. If you go too high on the CD to start with, the PS will run out of voltage needed to push the set amperage. Run time for 1 mil at a 5A CD will be 144 minutes.
