I put some more money and love to the project this weekend so I traveled the entire city to find these hugeass copper rails, some proper 4AWG cable, screws and blank PCB slates for the project to look better and more tidy.
As the previous attempt was a failure I'm redesigning the circuit for the MOSFETs to have proper heat dissipation now.
Also, today received some little MCP1407s to drive the MOSFETs with, so I have a little question:
I have seen schematics which use one driver for each MOSFET and others which use one driver for all MOSFETs. Can I be stingy and drive all MOSFETs with just one MCP1407? Their model is still IRF540N. The IRFB7430 are still on their way.
