We have some new ones from other users we think have some good ideas behind them and fit with our experience of keeping things simple and understandable. I think a fellow RV10 builder has already shared his design with you and I should have a revised copy of that to share soon.
I saw an early preliminary design. It really wasn't applicable to my setup which will incorporate VPX and have dual alternators and batteries. I've come up with a what I think is a good design but am trying to get it onto a decent CAD format so that I can ask for a critique.
