Thank you for the information. I am looking for a power supply to eliminate the need of charging my (2) 5000mA batteries. You mentioned a HP 50A unit - is there risk of tripping breakers or will the starter box only pull 10-15A current. I am not sure what power supply current will work best. I saw this one recently...

ALITOVE 12V 15A 180W Power Supply Transformer Switch AC 110V / 220V to DC 12V 15amp Switching Power Adapter Converter LED Driver for LED Strip Light CCTV Camera Security System

Sorry - the forum won't let me post links or pictures yet

I thought maybe I could just add a 110v cord and +/- banana plug leads for the power box. Would this work?
Thanks,
Mike
