Charging an Aux battery with this?

I'm setting my JK up for some camping. I need a CPAP, so I have a deep cycle Marine battery in the back of the jeep in a battery box.

The best solution (cheapest) I've come up with is this.
https://www.amazon.com/Stinger-SGP32.../dp/B001HBYXVS

Running a heavy wire (4/0, 1 AWG, ?), a fuse or two, back to the battery.

It should allow me to charge the Aux battery and Jeep battery while driving, not drain the Jeep battery while using the Aux Battery, and if needed, can bridge it to start the vehicle if the Jeep battery is dead.

Any suggestions, other ideas, etc.

thanks in advance.

Your best bet is a Battery Doctor battery isolator.
I bought a 70A. model at NAPA for around a hundred bucks.
Simply hook it up and forget it. No switches or fooling around trying to remember which battery is charging or needs charging.
I have a dual battery setup to power my winch and the isolator keeps both batteries charged. If I run the second battery flat with the winch, the first battery will still start the Jeep.

Good Luck, L.M.

I clicked on your link and scrolled down a bit. There's a 70A-100A (probably the newer version of what I have) for $53.78.
Free shipping if you're a Prime member & (I expect) no tax.

Good Luck, L.M.

Im getting closer to purchasing and setting up a charging system for boondocking. Once complete, I'll post the results.
