Loving your setup. I wanted to do a dual battery as well but all the kits pointed an install where I wanted my arb compressor. But your solution is legit. I need to look at sourcing your parts. It’s exactly what I’m looking for. 👍🏻👍🏻
My twin brother and I will be doing a dual battery "how to" guide with all the details. From terminals, to making your own battery cables (custom fit length) to isolator/controller setup, etc. Coming soon...
