[Elecraft] Batteries for NPOTA Activation with KX3

[Mark Tosiello]

Hi,

I'm planning an NPOTA activation using my KX3 on SSB and CW, running max
output without an amplifier. My antenna will be an inverted V at 30', and
I'd like recommendations for a battery technology and brand, assuming I
don't use the internal batteries (I think I would rather not).

I'm looking for something that will work with a KX3 as well as an IC-706
MKIIG. Ideally, I'd like to get several hours out of it if possible, but I
do know that that's hard to say based on number of contacts and SSB/CW.

What's the best method of making a connection from said batteries to the
KX3? I suppose powerpoles to the standard KX3 connector would be idieal....

Anyway, thanks so much!
