Hi Don, Thank you for the reply. Is there an ideal voltage under TX/ load? 13.8V under load is easy, so is 14.5+. If there's advantage to running higher voltages, I can, but if there is no advantage I'll just target 13.8 under load and call it a day and not worry about dropping voltage for other components.
