[Elecraft] Re： Internal battery for K3/ QRP

[Johnny Siu]

Hello Ignacy,

Yes, correct, I am thinking of using Li-Po pack which is cheaply available in 
Hong Kong.  BTW, are there any ways to keep the standy current of K3 down to 
minimium?  Perhaps, some of the experienced K3 users may have a cue.

Li-Po batteries can be charged by multifunction intelligent charger which is 
also cheaply available as well.

cheers,

Johnny VR2XMC

I think that SLA is too heavy LiFePO4 battery packs are much more efficient
yet have a max voltage around 14.5, within the K3 specs. A 6A pack, e.g, as
in 

http://www.batteryspace.com/12-8v-lifepo4-battery-packs-from-6-6ah-to-9-9ah.aspx

may fit inside the KPA3 space and may be good for a few hrs of operation.
These batteries need a charger with a limit on max voltage and max current,
but a simple voltage regulator + a wart or a laptop PS will do.
