Thanks Joe, but how are you able to tell that these regulators have a highe
r set point?

I have a John Deere regulator in my RV-12. The system voltage is now a half volt
higher than when using the Ducati regulator. Not saying the regulator that
you buy will have a higher voltage, but for $25 it is worth a try. The Ducati
regulators fail so often that some pilots carry a spare. The important thing
is to mount them with heat conductive paste to help carry the heat away. Heat
is the enemy of electronics.

I've had two of those PM rectifier regulators consistently put out 14.4
volts (+/- 0.1)
Mine were purchased directly from John Deere although I doubt that
matters other than doubling or tripling the price.

If it's a potted assembly, like many small pm rectifier/
regulators are, then adjusting the setpoint is not practical
and pretty much impossible. If it can be disassembled and
the parts are accessible, it MAY be possible to make
some adjustment to the voltage control circuits.
Actually, you might consider leaving it at 13.8 . . . if
indeed it really runs at that value or a tad higher.
See https://goo.gl/vCd59M
Note that the LiFePO4 cells will achieve 100% charge
or very close to it with a charging level of 3.4v per
cell (13.6 volts on the bus). But as the experiment
shows, there is a tipping point at about 3.3 volts
per cell that severely limits energy replacement
in the LiFePO4 cells. So if you're running 13.8, you
can probably leave it alone.
