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,

Comments, suggestions & experiences of other outdoor QRP ops are most
welcome.
Missing from your analysis are NiMH batteries, which i believe to be a
viable alternative to LiPo cells. I don't have access to a West Mt.
Battery Analyzer, so I can't offer a detailed analysis. Perhaps you
can add that to make your analysis more complete. One advantage NiMH
batts have are lower cost, OTH I suspect they weigh a bit more.
An import consideration WRT to LiPo that you fail to mention is
charging requirements. LiPo has had problems with charging, sometimes
catastrophic. It is VERY important to follow the manufacturers
recommendations and use the proper charging equipment.
