[Elecraft] KX3 batteries

[Chris Waldrup]

Will the Bioenno batteries have enough terminal voltage to get the 15W?
I'm looking at a 9Ah unit and if so will stop by Gigaparts on the way home from work today and pick one up.

They both have the same specs for "Internal Impedance (after discharge to E.V.=1.0V)”: Approx. 25mΩ(at 1KHz). I have to admit that I have no idea what that means.

In my experience, using both of them sequentially, the KX3 went more quickly to the enforced 5 watt maximum output with the Eneloop Pro cells compared to the standard Eneloop, despite the higher ultimate capacity of the Eneloop Pro. But, YMMV!
