[Elecraft] Batteries for K1.

[David Quental]

Hello all,

I have a lovely K1 and I am about to start my SOTA activitions, maybe 
next saturday. My K1 has a KBT1 an Internal battery Adapter and I have 4 
rechargeable batteries at my own. What could be better, buy more 
rechargeable batteries or a small battery, however bigger than AA 
batteries, to operate with ?

Any answer will be welcome here.

Best 73 to all.
