Dual battery setup?

[Muddy Bean]

Put a 1000 amp AGM in and call
It a day. I had a group 31 battery in my Land Cruiser before I traded it. When my Expedition battery dies (it’s an AGM) I’ll put in a group 31 agm in it.

You have to be careful with the agm batteries:

I knew I remembered someone doing a dual battery setup before...

You can also do a remote battery like the kayak fisherman use, I just put the box in the back when we travel and plug it into the rear power plug to charge it. Here is an example, , mine has a couple of these in it https://www.amazon.com/gp/product/B002V3JITS/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 and will last a couple of days charging phones, tablets, etc. They are also handy to have around during storm season when the power goes out. I even have one that powers an old Sirius radio with speaker that we use when camping or tailgating.
