G'day there guys, I'm just wondering if anyone out there had installed a ArkPak 730P, or equivalent, into their vehicle to be a dual battery alternative. I have been trying to weigh up all the pro and cons of using this configuration, so any input would be great. ArkPak also recommended using a dual battery wiring loom, with a voltage sensitive relay/solenoid. Any suggestions? Thanks guys your input is greatly appreciated. Cheers Nath
