You might find the LCD screen is fined up to 14.4V, the ones we use have internal LDOs for the logic/comms circuitry anyway, and just run the backlight off the supply (which is through PWM anyway).

I've found some of their stuff isn't that flash on living up to specs. High power being some of the trigger words. Helps to get some known good shit from digikey or similar to compare with. Compared similar for LED strip though, 5m delivered was about the same price as 30cm local So with the money saved I bought 5x what I needed, and some RGB indivdually programmable RGB strip. Money was not saved
