Elecraft K1 KBT1???
I prefer an external power supply/regulator. No one has mentioned
the Pulsed Charge Regulator from Bob Lewis, AA4PB and his QST mag.
article of May 2001. This acts as a power supply but functions as both a
charger/
regulator. I have had this style of power supply for the Elecraft K2 and K1
since 2001.
"The PCR12-500A is a self-contained charger designed to automatically
maintain a 12 volt Sealed Lead-Acid battery having a maximum bulk charge
of 500 mA or greater. The Power Sonic PS-1229A is an example of the type
of battery this charger is designed to work with."
Bob Lewis, AA4PB, An Automatic Sealed Lead-Acid Battery Charger, QST,
May 2001, p. 43-47.
Another type of battery that is useful is a Camcorder Replacement Battery--
Panasonic 12 volts, 2.3Ah. It is similar to the Power Sonic PS-1229 and
PS-1220.
