I'm running a dual battery setup, pieced it together from various parts. Running a Northstar Group 35 battery on the passenger side with a OffGridEngineering Aluminum mount. The Group 35 battery is wired into the truck/starter and is the main truck battery. On the drivers side I'm running a Group 31M Northstar with a Pelfreybilt stainless steel mount. I modified the mount by welding studs onto the top of the mount to hold a BlueSea ML-ACR (Automatic Charging Relay). The ACR automatically combines when the truck is running and keeps the 31M topped up, I can also manually force the ACR closed to tie the battery together for jump starting or high amperage situations like winching. The ACR is good for 500A.

I'm also running BlueSea low profile fuses on each end of the positive cables.

If you needed to, could you jump start the primary with the secondary?

This is my next upgrade, been looking into doing dual battery, this way I can not worry about draining my battery with the ARB fridge I want to run. This and a 100w solar panel.

I too amlooking into this or a larger single. Getting a winch and a fridge one day. The self starting jump start is also handy

Anyone running a dual battery setup side by side? Just wondering if the front end would support all that extra weight.

Great idea with using the Pelfrey Built battery holder with OGE secondary holder together.
