[Elecraft] Internal battery options for K1 & K2

[Bryan Nehl]

 Let me just put this out there:
Custom LiFePO4 18650 Battery: 12.8V 4500 mAh ( 57.6Wh, 7A rate ) w PCB and connector (batteryspace.com)
There is a wiring option to select for the K2 as well.

  That's a good point.  My knee-jerk response is to go with rechargeable rather than (horrors!) disposables.  Way back, I did a fair amount of portable ops, so rechargeable made sense.  Now, IDK.  I'm just getting back into to it. For me, figuring this stuff out, deciding on an optimal solution, rigging it up, and making it work, is more fun than actually using it. HI HI.

 I'm thinking 4 individual LiFePO4 cells in the K2, maybe 4 ea 32700 @ 6 Ah and 1.3 lb,? LiFePO4 being less fraught than LiIon.?

Have you considered non-rechargeable AA Lithium batteries? Expensive, but they are available in every grocery store, last forever when not used, don’t leak (hopefully). Good for occasional field use, maybe?
