[Elecraft] [K2] KBT2 Battery charger/power supply recommendation?

[Don Wilhelm]

Dick,

As an alternative, you can make a direct connection to the battery (put 
a fuse in for safety please) and use one of the SmartChargers to keep 
the battery topped off.  Take a look at my website article at 
http://w3fpr.qrpradio.com to see how I did it.
