The PD9280 does 14.8? ISTR 14.4.
It's been modified to change the "boost" voltage to 14.8v. The other voltages are unchanged. It's a simple modification of soldering a single resistor across the voltage sense. I installed a potentiometer (10 turn trimpot) to adjust it to 14.8v to match what Trojan recommends.
