OK time for me to expand this cars travelling luxuries. I need to organize and get a dual battery system fitted. So I need to know if this is the right path to go.
I don't need anything extravagant. I'll only be running a fridge and a few lights at the back for now anyway.
This is what I've come up with.
Already have a battery tray under the hood so this is already done.

- Redarc BCDC 25A unit with MPPT for future solar provisions if I ever go down that path.

- At the back I'd like one of these units. I'll be running an ARB fridge so, this has an engle socket ready to go, as well as a few other bits. And fits nicely in the corner at the back.

- Battery? Now this is my biggest puzzle. Recommendations are most welcome. As above, I'll running a fridge, few lights, charge a few phones etc... Nothing special. Something around 100Ah perhaps ???

Shoot me with opinions please.
