  • Why should all the main wires to and from the Mosfet be the same length? ZeroFossilFuel doesn't do this in his V2.1H?

  • I have seen ZeroFossilFuel Video on V2.1H. His wire on the Drain is about 1.5 inch longer on one of the MosFets, this is acceptable. The source wires look equal. Now to answer the Question. The MosFets form a Parallel Network each leg has the resistance of the MosFet Plus the wires connecting them. When these networks are out of balance one MosFets will work harder then the others and generate more heat, shorting it life, When one fails completely the others will follow shortly.

  • Around 30Amps Max and 25 nominal.

  • This PWM can handle much much more!
