You could put a switch across the diodes so that you can shunt around them when
the battery voltage reaches a safer level.

"You can connect diodes in series with the power input. The voltage drop
will e the junction voltage plus the the IR drop due to the current. You
can find out the total drop by measuring the current drain and going to
the spec sheet on the diode used. The spec sheets can be found by doing
a Google search on the part number of the diode used.
