[Elecraft] My 13.8 Volt Solution

[KK5IB]

I run a K2 and a K3 mostly QRP, powered by an Astron SS-30M power supply. I
also have a 55 amp AGM deep cycle battery for indoor use. All the above are
connected through an KI0BK Low Loss Power Gate. The power gate has five
Anderson PP connections, battery in, power supply and three out. When the
power supply is on the battery is charged with small current, when the power
supply loses its input power, the power gate shifts to battery power in
microseconds. The power in connections are hot swappable. The power supply
and battery are isolated from each other so that the battery will not be
discharged by the power supply bleeder. The power gate has 25 max amps
capacity which is fine for my situation. Hope this is of interest.
Darryl, KK5IB
