While Don Brown has offered an alternative to increase the voltage of
the controller, I would not recommend doing it that way - what you end
up with is a solar controller that is specifically modified to use with
the K2 only.
I would want the solar controller to work with any 12 volt Lead Acid
battery and the charger modified for this K2 use would overcharge a
battery connected in the normal way.
If I did modify a controller to have a higher output voltage I would
mark it in BIG BOLD letters to serve as a caution against connecting it
directly to a battery - I know such mistakes do happen.
Don B. did say that the direct battery connection inside the K2 is the
best method, and I fully support that.

The other way
to solve the problem is to increase the controller switching point to about
14.5 volts by installing a 220K resistor at R9. I have not tried this but
should work. The controller would plug directly into the K2 power connector
to charge the battery. If you use this method then the controller should not
be connected directly to the battery.
