I have always been a KISS proponent.

I have however recently been using the Powerbox on large planes (35%+) . While on the surface it looks like an expensive "do-dad" it simplifies a lot of the rats nest wiring in the plane and combines several functions into one. I only use Li-Ion power and would never even consider anything else.. Li-Ion power is THAT GOOD. So by using the powerbox I combine battery load sharing, comprehensive battery monitoring, power fail safe / redundancy, servo output ampification, RFI reduction on long leads and receiver isolation. It is a complete power redundancy system and it is all controlled by one solid-state switch with nothing to vibrate loose or create RFI. It weighs less than the regulators and wiring it replaces!

Yes, its pricey $350 but I only need to buy it once, and it truly has made life simple. Its a waste on anything less than 35% though.

In this case I believe more is less. The cleanliness of my equipment installs is as good as it gets and I have plenty of clean power all around.
My engine off vs. engine on ground range has improved dramatically as well.
