You never posted if you solved your problem, but I believe that there is a way to boostrap two 70 amp Astrons together to make a higher capacity supply - there's some sort of interconnect made between the two for control.

You did not post what make/model amp you are powering, but I know that most of the 12 volt amps draw well over 40 amps average on SSB so I can believe you might exceed the 57 amp Astron rating. The SGC Power cube is rated 500 watts, 40 amps SSB, 80 amps CW key down - so that 40 is an average.

I suspect you find the battery in parallel with the power supply to work fine - and it should - the battery will be quickly recharged during receive as the amp meter will tell you. With a 100 amp/hour battery you are probably doing fine. With a 220 a/hr you should be excellent.
