[Elecraft] K2 Battery Alternative?

[Don Wilhelm]

Deni,

It should work fine, especially if you keep the power to 5 watts or 
under.  Set the CAL CUR parameter at 3.50 Amps to avoid HI CUR warnings.

If you try to run at 10 watts, the IMD will be reduced and the current 
draw will be excessive.

Remember that the K2 tries to produce the power requested by the POWER 
knob, and in order to maintain that power at reduced voltage, the 
current must increase.
