[Elecraft] KBT-2 out of radio battery charging

[Don Brown]

Hi

You could use one of my solar controller kits and a 15-18 volt wall wart or 
power supply in place of the solar panel. You would just need a 5-10 ohm 10 
watt resistor in series with the wall wart to limit the current and make the 
supply simulate a constant current source like a solar panel. I still have a 
few of the low current 1.5 amp versions left at $16 or the 16 amp version at 
$30. For this application the low current version would be fine. This 
controller is designed to keep a SLA battery charged and can be left 
connected to the battery indefinitely
