[Elecraft] K1 Dumb Question

[David Toepfer]

I think he meant simple diodes rated to handle the power you will use.  Each
biode should have a voltage drop of 0.6V, so 2 would total 1.2V drop and I
believe that would be current independent.  Placed in series the battery shuld
just see it as part of the load and not be concerned.
