Fwd: Re: [Elecraft] battery backup, etc. for QRO K2?

A better technique is to use a power supply that is designed to float 
across and manage batteries. They call them RV Converters. They are 
very cost effective, and at least some of them are very RF quiet. No 
diodes are required, and the supplies are designed to withstand the 
loads and voltages of batteries connected across their output 
terminals. I recently put together such a system and made a web page 
with some of my experience. The one I have is rated at 60 amps and 
together with a 100 amp hour AGM battery powers several rigs and 
occasionally even a solid state amplifier requiring up to 100 amps. 
It has a Charge Wizard to manage the voltage profile to properly 
charge and maintain the battery bank, which a fixed voltage cannot do:
