[Elecraft] Battery use with QRP rigs - page updated

[John Harper]

Rod,

I haven't tested NiMH batteries yet and probably won't since I don't own any 
and can't justify the expense in purchasing them + another charger since I 
already have a growing LiPo collection. However, if someone wanted to send 
me a NiMH or two, I'll gladly test it/them, post the results and pay for 
return postage - as long as they email me first and let me know. That way I 
don't get redundant batteries...;-)

Regarding the charging of LiPos: you are correct in that a dedicated charger 
is needed and that the manufacturer's instructions should be followed. The 
links I posted at the bottom of my page were meant to address this (and the 
many other) aspects of LiPo batteries  - I'm only interested in describing & 
comparing their behavior in regards to my recent QRP operation and the 
previously-used alkalines. Google is available to those seeking more info 
than could possibly be contained on a single website.

Thanks and 73,
