I have been running a SBI12 Voltage sensitive solenoid and booster diode in my Prado 150 for a few years. It has worked well as far as charging goes. But I think the standard charging circuit id not the best for charging batteries from low voltages ie deep cycle and camping. I ruined a battery in around 2 years.
I decided to go with a BCDC charger and use the solenoid just for linking the batteries for jump starting.
This video just shows the installation and testing.

Best option for some cases is to buy an inexpensive, but good isolator (about 40 USD e.g. Stinger SGP32 200 AMP) then you have about 400 USD to spare to buy new batteries. Even if you short the optimal life span of your batteries in half; most good batteries come with a 3 years warranty so you can get new ones for free or use the money that you saved to buy them.

I also added mine to the front in front of the radiator. I did find that it was getting hot and it would back off charging.

Waste of money for this application in my opinion. DC to DC charger only worth it if you have more than one auxiliary battery or if you have expensive agm, lead crystal or lithium batteries. A basic VSR with override function hooked up to a 100ah deep cycle lead acid is perfectly fine. Your batteries life cycle will be a result of how you treat it... If you're always depleting it below 50% and using your vehicle on rough off-road outback trips then you'll get shorter life cycles no matter what charge system you use.

Now I can go Lithium if I want to, I can also use the MTTP solar input that gives me about an amp more than my PWM controller on the Panel. Lastly, I just wanted to fit one to have a play with it.
