Were can I buy a rheostat? and what type do I need?

[neil]

Question? - I want to use a 300 amp battery charger with 12v output for plating chrome. Does anyone have a idea where I can get a rheostat that size and what type to use? Thanks for any suggestions.Neil

rheostat

Have you looked at the salt water rheostat in the manual? It looks really amateurish, but really does work very well and is dirt cheap to set up.
