not to sure on how to properly set up a battery charger for annodizing i have the charger wired to a dimmer switch to de rate the voltage but how do i de rate the amps as well? or will the dimmer also derate the amps to?or am i just shooting myself in the foot? should i just buy a rectifier and be done with it ?

See page 5 of the LCD anodizing instructions. By reducing the voltage, you are also reducing the current, since V=I*R (Ohms Law).

If you have a battery charger already, dimmer switches are very inexpensive and can be tried to see if you like it. I personally prefer the automation of a Constant Current power supply. I no longer have to watch the anodizing tank, just set a timer and Presto! Great results every time.

You're going to want to use the 12 Volt settings, probably 12V/6Amp unless you are doing very small pieces. Using LCD anodizing, you're wanting to run the parts at 4.5 Amps/ft^2.

Also, a couple of question marks and periods might help, too.
