Diodes - @9B - Yep. Watch out for those lost volts. Regular 1N4xxx series diodes commonly used are even worse than Schottky! And you can also loose volts by using too small of wire (14ga for the main run), or too small of breakers. Breakers? Yes, breakers. Stick with 5A breakers or larger as even 4A breakers loose 0.3V and 1A breakers are awful loosing 1.1V (Klixon spec max voltage drop)!! Who knew?
