I have 3 batteries connected in my ute.
The first battery (starter battery) is connected to a auxiliary battery.
The auxiliary battery is connected to a 3rd battery.
The connection between the starter and auxiliary battery is also via Redarc isolation switch.
The 3rd battery is connected to a 30 amp solar charger.
I assume that the isolation switch will keep all 3 batteries charged whilst I am driving.
When I am stopped for a week or more I am relying on solar power to keep all 3 batteries charged.
The connection cables between the batteries are heavy duty battery cables.
Question to the electrical experts, is there a problem with this setup ?
