[Elecraft] Need suggestion for K1 external rechargeable battery

[Rich]

If hiking is your issue, you might want to consider a LiPO battery like 
ones used by model helecopter inthusiasts.  I've been using a 950 mAH 
Blue LiPO for several months, once a week for a 1-1.5 hour morse code 
practice.  I've been expecting it to run dry, but I have not recharged 
it yet.  I have not had a timer on it, but would suspect I have at least 
6 hours on the battery, running a K1 at 1W.

I went this route on advice from a SOTA operator who wants extreme low 
weight.  Battery weighs about 65 grams.  You do need a special charger.  
Battery costs around $6-10.  Charger/balencers run $20-40.

OK, I also bought a 2200 mAH battery for a backup.
