I am installing a hydrogen fuel cell in my old car and need a way to control power usage. Power will be coming from the car through a 40A automotive relay, though I currently only need about 15A I want to be able to expand to 30A later (with bigger cell). Power adjustment would work with lowering current or lowering voltage (which would cause cell to draw less current), whichever would be more easily and inexpensively done.
I have found this which looks like it would work, but I can only find ones that ship from China, and was hoping for something cheaper and smaller.
Any help would be very appreciated.

BTW: I have a good multimeter and I can solder.
