So i was going to use a voltage cuttoff like this to power a relay
**broken link removed**
how ever i was not thrilled about the current draw across the relay, so i found that you could use a IRF4905 to make a solid state high side switch no draw
.... so i drew this up
**broken link removed**TV
now i was drawing up my board so i could etch it and it hit me, can the PCB handle the draw im putting through it? the mosfet is rated to 5-10A (total as drawn 10-20A). the battery is 2.3A @ 12V(i know its over rated its an idea right now) now if i were to apply that load to it would the etched board take it with out acting like a fuse and burning up?
