Default Solar panel charging 12V battery - prevent over charging

Now it seems to have charged the habitation battery, or at least is happy
that the habitation battery is charged, because the LEDs show that it is
only charging the vehicle battery.


Habitation battery is at 13.8V, vehicle battery is showing (through the
Sargent EC450 controller) charging at about 0.2A with a voltage between
14.5V and 14.6V.


Neither of those figures makes sense. A fully charged battery after left
to settle for a while doesn't read anything like 13.8v That is the figure
you'd see when on a float charge.

And a ordinary car battery with 14.5v across it will take a lot more than
0.2amp.

You need to measure the actual battery voltages with a decent DVM.
