My pleasure.

That guy in the YouTube video (Mark Erickson) was wrong about needing to match the impedance between batteries. The fact is battery impedance is of little to no concern. I have sent Mr. Erickson three pages of quadratic equations to substantiate this.

I know what some of you may be thinking, you are wondering, "what about FFT?".

If anyone suggests using Fast Fourier Transforms as a viable argument, I think I'll vomit. Only a noob would think that doing a time domain / frequency domain speculative comparison for the sake of conversion efficiency or as a substitute to empirical bench testing has any place in this process whatsoever. Please leave this out of it:

Thank you.
