I would like to  make use of this ample resource of ELECRAFT
knowledgeable  persons  available  , to clear up an issue of how to use
my K1  w/ internal battery pack properly. 

ELECRAFT urges the practice of not charging the battery pack  KBT1 
while sitting  in the K1 itself. I assume it is for thermal reasons.   I
have found  that  it is kind of a hassle to take out the 4 screws
holding the top ,  pop out the pack  , remove the 8  AA cells , 
recharge them , reinstall , etc...           What if one recharges  them
 ,  while still in the K1   ,  at reduced charge rate , like say  10 C  
or 20 C   rate  , perhaps around   100 ma  or so    ,   for a   typical 
1200 maH   cell      ?     And monitor what that would do to the
temperature of the pack by feeling of it for a test ?   If the pack is
just mildly warm  , feed the charge line in the  12VDC Aux line ,  set
it for  a low sort of trickle rate   60-100 ma  , and do away with all
that hassle. 

All comments / suggestions    gratefully received.
