[Elecraft] [K2] LiFePO4 replacement for internal SLA battery in K2

[Bill W4ZV]

Hi Steve,

I'm following this topic with great interest!  I've been using my K2 for
extended operations (8 hours) from SOTA summits and have been lugging a 5
pound 7AH SLA.  Needless to say I'm very interested in going on a weight
diet for the K2!

I've had good success using external 1AH LiPOs for smaller rigs (ATS-3 and
Weber Tri-Bander) but they're CW only and band limited.  They're also very
inflexible for quick band/mode, where the K2 shines.  I've had zero problems
with LiPOs but I religiously charge and store them per manufacturer's specs. 
I'm also a little leery of internal batteries of any type.  Since I already
have a balancing charger for LiPOs, I've been considering a larger capacity
LiPO (e.g. 4.5 AH available on eBay for <$25) for the K2.  For comparison,
this battery weighs <12 ounces versus the 5 pound 7 AH SLA, so it weighs 86%
less and probably has sufficient life for most of my operations.

I'd be interested to hear any comments from others about any leakage
problems with internal batteries.

73,  Bill  W4ZV
