Hey gents-
Looking into doing a basic dual battery setup on my 2020. When I say basic, I mean not extensive power management or anything. Just something to monitor both batteries and keep the 2nd charged when the car can handle it or when needed.
One of the questions I have is about battery types. Right now, I have the stock battery in the 4runner which is just a standard lead-acid. What I'd like to do is add a second battery and maybe have it be AGM (Odyssey or Optima).
My question is whether or not you can run a setup that has two different battery types on it like that, or if I'd have to swap out the factory battery as well this early into my owning the truck. Can you run different types? I know car chargers and maintainers like the CTEK typically require you to select which type of battery you're running (conventional, AGM, etc.). Basically, I don't know enough about this stuff yet to make these sorts of decisions.
Another question I have for people is how you manage getting so much wiring through the firewall for all sorts of accessories. I know that a lot of people will run S-Pods, etc. on the engine-side of the firewall to consolidate wiring, but there's still some stuff like wiring for fridges, power hubs to run accessories like tablets and phones and radios, etc.
What I'm finding right now is that I can't really run everything I have through the two firewall openings on the driver's side. Do people drill more holes in the firewall to deal with problems like this?
