[Elecraft] KX3 Battery Life

[Fred Jensen]

I don't have a KX3, but using my K2/10 @ 5W on CW, I've managed steady
operating for at least 2 hrs with an A123 4S1P LiFePO4 rated at 3.5 Ah
and I've never depleted the battery.  I believe the KX3 is a bit more
efficient than the K2.  I also believe if you restrict the power to
2.5W, the KX3 uses a more efficient PA output circuit.
