no where near enough information. Purpose of circuit, number of additional circuits, are you tying into an existing circuit designing from scratch, Constant circuit, power option circuit (Turn signal, window, alarm) come on throw us a bone here Building a camping stove ehhhh? 12 volt D.C. heavy duty switch 60 ampre should suffice. Around 10 bucks 12 foot spool of 10 guage wire 15 bucks 10 guage inline fuse holder with 50 amp fuse 12 bucks Package of assorted wire ends 14 bucks (or solder and/or soldering iron) price of element unknown (never bought one before) Interstate Battery re-manufactured $25, new $90, deep cycle new $125 60 amp rheostat (to control temperature) 45 bucks Assuming you are talking about a heating element
A circuit to do what? 12 volts could power any kind of circuit, from a simple light bulb connected to a battery, to an entire car with complex audio and security systems. What are you talking about specifically?
Easy, the battery itself, a charging source (alt, generator, battery charger) some 8 awg wire to connect it to the battery and enough brains to know how to wire it. :)
